Hajj, one of the five fundamental pillars of Islam, is obligatory once in a lifetime for every Muslim who has the means. However, due to physical disabilities, old age, financial constraints, or health issues, millions of Muslims are unable to perform this fundamental duty. This is where revolutionary change through modern technology opens new doors. The integration of Augmented Reality (AR) and Digital Twin technology gives rise to the concept of “Digital Twin Hajj,” which promises to make the spiritual journey of Hajj accessible to millions worldwide who are traditionally deprived of it. This concept is much more than a virtual tour; it is a dynamic, sensorially rich, and spiritually emotional experience that presents every aspect of Hajj—Tawaf, Sa’i, standing at Arafat, Rami al-Jamarat—in the comfort of the user’s home in such a way that they feel completely present in that sacred environment. This article will delve into how AR headsets, haptic suits, and digital twin technology together can create a comprehensive system that not only removes physical barriers but also enhances its educational, emotional, and social benefits while preserving the spiritual essence of Hajj. This is the first comprehensive and forward-looking analysis on this subject presented in the world.

A significant population of Muslims worldwide suffers from some form of disability. According to the World Health Organization, more than 15% of the world’s population lives with some form of disability. If we apply this to the Muslim world, this number would be in the tens of millions. This includes elderly people for whom the physical exertion of Hajj’s lengthy and patience-testing rituals is not possible, individuals without financial resources, people suffering from chronic diseases, and women who have no mahram to take them for Hajj. This is a silent majority whose voice is often unheard. The physical strength, financial capability, and logical capacity required for traditional Hajj present an insurmountable barrier for them. The concept of Digital Twin Hajj through AR completely eliminates all these barriers. It presents an inclusive solution equally accessible to rich and poor, young and old, healthy and disabled alike. This is not a hypothetical concept but a solution to an immediate human need that builds a bridge between technology and mercy. The need becomes even more urgent as climate change causes temperatures to rise extremely high during Hajj days, which can prove fatal for many pilgrims. AR Hajj eliminates these risks while providing a safe environment.

Digital Twin actually refers to the virtual replica of any physical system, process, or product that continuously interacts with its physical counterpart through real-time data. In the context of AR Hajj, an extremely accurate and detailed 3D digital replica of all holy sites in Makkah and Mina will be created. This will not be mere cartoons or animation, but a digital world created through high-resolution satellite images, 3D scanning, and drone photography that will be closest to reality. In this digital twin, every stone, every wall, every step will have the exact same measurements and structure as present at the actual sites. This digital world will be superimposed on the user’s actual environment through AR headsets (such as Microsoft HoloLens or Apple Vision Pro) in such a way that they will feel themselves standing in the courtyard of Masjid al-Haram while walking in their room. The digital twin of each ritual will correspond to its real counterpart—the exact size and distance of the Kaaba during Tawaf, the actual distance between Safa and Marwah, and the expanse of the plain of Arafat. This exact replica is the key to maintaining the truthfulness and spiritual effectiveness of the experience.

The technology ecosystem required to enable the AR Hajj experience is extremely complex and advanced. At its center will be a high-resolution AR headset that will bring 3D objects of 4K or better quality before the user’s eyes. This headset will have spatial mapping capability, meaning it will understand the geometry of the user’s room and place digital objects in such a way that they don’t collide with real furniture. Haptic gloves and suits will give the user the sensation of touching the Black Stone or wearing Ihram clothes. Spatial audio technology will ensure that the sound of recitation is felt coming from every direction with the echo of Masjid al-Haram, exactly as it happens in reality. Olfactory display systems (if religiously permissible) can simulate the specific fragrance of Masjid al-Haram through scents. All these technologies together will create such sensory immersion that will be sufficient to convince the user’s brain that they are truly present in Makkah. This experience will be much more real and spiritually effective than current 2D videos or VR.

In the AR Hajj system, every ritual will be presented with its complete details and juristic accuracy. During Tawaf, the user will see the Kaaba revolving around them in their AR headset while walking in their empty room at home. The system will track their walking speed and number of circuits, and if they get too close to the Kaaba, haptic feedback will stop them. In the Sa’i ritual, the user will have to walk between Safa and Marwah, where 3D models will show them the actual shape and distance of both hills. During the standing at Arafat, the system will show the user standing in the vast plain of Arafat, where the digital twin of millions of pilgrims will be present, creating the real feeling of collective worship. For Rami al-Jamarat, the user will pick up real stones (or their lightweight alternatives) and throw them toward the pillars visible in 3D, and the system will check whether the stone hit the correct target or not. Before each ritual, the system will teach its conditions, pillars, and Sunnahs in detail, immediately alert about mistakes, and help correct them. This is not only an experience but also a complete educational and training platform.

The juristic justification is extremely important for the use of any new technology in religious matters. Looking at the concept of AR Hajj from a juristic perspective reveals several aspects. The first question is whether AR Hajj is sufficient for fulfilling the obligatory Hajj? The answer is negative, because physical presence and actual performance at specific locations are conditions for the obligation of Hajj. However, this concept can prove very useful for several other important purposes. First, it is an educational and training tool for those who intend to perform Hajj in the future. Second, it is a source of spiritual comfort for elderly or disabled people who have performed Hajj but are now unable to go again—this can become a means for them to refresh memories and maintain spiritual connection. Third, it can create desire and passion for Hajj in young people who don’t yet have the means for Hajj. Scholars agree that if it is seen as an educational, training, and spiritual supplement rather than an alternative to obligatory Hajj, its juristic justification is clear. This is exactly like watching videos to learn prayer or using apps to read Quran.

In the modern era, especially for Muslims living in non-Muslim countries, maintaining spiritual connection with their religious centers has become a challenge. The concept of AR Hajj can play an important role in filling this psychological and spiritual void. When a user is virtually present in Masjid al-Haram while sitting at home, their brain considers this experience real, resulting in the same spiritual peace and emotional attachment that occurs during actual Hajj. This sense of presence actually has a deep effect on the human nervous system, reducing mental stress and increasing spiritual satisfaction. For those who could never perform Hajj, this experience will strengthen feelings of love and devotion for Makkah and Madinah in their hearts. For those who have performed Hajj, it will renew their faith by refreshing their memories. This psychological benefit will be the greatest success of this concept, because it fulfills the basic purpose of Hajj—renewing connection with Allah—regardless of the means.

AR technology has now reached the point where it can bring users from different locations together in the same virtual space. This means that on the AR Hajj platform, users from around the world will be able to perform Tawaf simultaneously in the same digital Masjid al-Haram. They will be able to see each other’s digital avatars, greet each other, and participate in collective prayer. This opens a new door for the formation of a global Islamic community, where geographical boundaries disappear. An elderly person sitting in Japan can perform virtual Tawaf with their grandson in America. A disabled person can connect spiritually with other family members who are on actual Hajj through this platform. During Hajj days, this platform can also show live feed from Makkah in real-time, making users feel they are worshiping with current pilgrims. This collective aspect gives new dimensions to Hajj’s message of global and Ummah unity.

Hajj is a complex worship with dozens of rituals and related conditions and rulings. Many pilgrims make mistakes due to inadequate training. The AR Hajj platform offers the best solution to this problem. It will function as an interactive training system where future pilgrims can practice every ritual while sitting at home. The system will tell them what is the correct method of Tawaf, which prayers to recite in Sa’i, how to perform standing at Arafat. If the user makes a mistake, the system will immediately alert them and teach the correct method. This platform will be available in different languages, making it easier for non-Arabic speaking pilgrims to understand Hajj. Furthermore, it can also simulate Hajj procedures from different historical periods, helping users understand how Hajj rituals have changed over time. It will be like a living educational encyclopedia, providing deep insight not only about Hajj but also about Islamic history and culture.

The concept of AR Hajj is not only a spiritual service but can also create a new economic sector. The required software development, hardware manufacturing, and content creation will create thousands of new employment opportunities in these fields. Muslim countries, especially Saudi Arabia, can play an important role in the development and deployment of this technology. AR experience centers can be established in mosque complexes where people who cannot afford expensive AR headsets can benefit from this experience for a reasonable fee. This platform can promote Islamic arts and culture globally by presenting them in digital form. Every year during Hajj season, special programs and live sessions can be organized on the platform, for which users can pay subscription fees. This economic aspect will ensure the sustainability of this project and help develop it as a stable commercial venture rather than a charitable project.

Although the concept of AR Hajj is attractive, several technical challenges face its practical implementation. The first challenge is processing power. Extremely powerful computing systems are required to render detailed 3D models of Makkah in real-time, which are currently beyond the reach of ordinary users. The second challenge is latency. If there is even a small delay between the user’s movement and its effect on the screen, they may experience motion sickness. The third challenge is the cost of hardware. High-end AR headsets are currently very expensive. The fourth challenge is network connectivity. High-speed, low-latency 5G or 6G connectivity will be required for collective experience, which is not yet available in many countries. The fifth challenge is software development. Digitizing all Hajj rituals with their complete juristic accuracy is a monumental task. Despite these challenges, given the rapid advancement of technology, it can be expected that these obstacles will be overcome in the coming 5-10 years.

A phased roadmap is needed to give practical shape to the concept of AR Hajj. In the first phase, high-resolution 3D mapping of Masjid al-Haram and other holy sites will be done. In the second phase, a basic AR app will be developed that will provide users with a virtual tour of these sites. In the third phase, interactive simulations of rituals will be added. In the fourth phase, haptic devices and social features will be included. In the fifth and final phase, the system will be fully integrated with completely immersive AR headsets. Along with this roadmap, continuous consultation with scholars is essential to ensure that every ritual is presented with juristic accuracy. Cooperation with the Saudi government is also very important, as their permission will be required for mapping holy sites and data access. This is a long-term project that requires international cooperation, large-scale investment, and deep collaboration between religious and technical experts.

It is extremely important to consider cultural and religious sensitivities when digitizing any holy site. When designing the AR Hajj platform, it must be ensured that holy sites are reflected with respect and sanctity. No feature should be included on the platform that promotes disrespectful behavior with holy sites or rituals. For example, users should not be allowed to “fly” over the Kaaba or “ghost” inside it. Guidelines should be established for using the platform, clearly stating how to use it respectfully. Digital avatars’ clothing and behavior should also be appropriate. Safeguards should be built into the system to prevent misuse. It is this cultural sensitivity that will transform this platform from an entertainment video game into a serious spiritual and educational tool.

The concept of AR Hajj can also play an important role in protecting users’ mental health. The Hajj journey can be extremely stressful for many elderly people or those suffering from mental illnesses. Fear of crowds (agoraphobia), travel anxiety, or fear of unfamiliar environments cause them to miss Hajj. The AR platform will introduce them to Hajj rituals in a safe and controlled environment. They will be able to learn and experience every ritual at their own pace, without any pressure. For people suffering from diseases like dementia or Alzheimer’s, this platform can help keep their memories fresh. For post-traumatic stress disorder (PTSD) patients, it can serve as a therapeutic tool. This medical aspect further expands the usefulness of this concept and presents it as a comprehensive health solution rather than merely a religious tool.

The travel of millions of people during traditional Hajj results in significant increase in carbon emissions. The concept of AR Hajj offers a sustainable alternative. If millions of Muslims worldwide who wish to perform Hajj every year but don’t have the means obtain their spiritual satisfaction through this AR platform, it could significantly reduce air travel, resulting in reduced carbon footprint. This environmental benefit makes this concept important in the context of current environmental challenges as well. This is a solution that not only fulfills human needs but also helps protect the Earth.

The AR Hajj platform can be further expanded in the future. The first step could be to include holy sites of Madinah Munawwarah, such as Masjid an-Nabawi and Jannat al-Baqi, in the platform. The second step could be to include holy sites of Jerusalem, especially Masjid al-Aqsa. This will make the platform a comprehensive Islamic virtual ziyarah place where users can visit all three holy mosques. This will not only increase spiritual benefits but also enhance historical and cultural awareness among Muslims. Reenactments of important events in Islamic history can also be included on the platform, such as the event of Miraj or Conquest of Makkah, which will help users understand these events in a new and immersive way.

The concept of Digital Twin Hajj through Augmented Reality actually lays the foundation for a new relationship between religion and technology. This is a comprehensive solution that makes spiritual experience universal while removing physical barriers. It is not only a mercy for the disabled and elderly, but can become a powerful source of spiritual unity, educational development, and cultural preservation for the entire Muslim Ummah. Although there are several challenges in its path, the passion for serving humanity and spreading the faith will provide the necessary strength to overcome these obstacles. This concept is taking us toward a future where technology becomes not merely a tool but a means of mercy and guidance. This is that future where no person, in any circumstance, remains deprived of connecting with their Lord and visiting His House.
