The fifteenth- to sixteenth–century Sufi mosque of Langar Ota is located in a mountainous region of Uzbekistan, 104 km southwest of Samarkand, historically one of the most important cities of the Silk Road. Although Sufi shrines, mosques, mausolea, and lodges are known and preserved in urban centers of Central Asia and the Silk Road such as Bukhara, Samarkand, and Shahrisabz, the Langar Ota mosque is one of the few rural Sufi mosques in Uzbekistan that has survived mostly intact since the fifteenth century, when it was built during the reign of the Timurid dynasty as a khanaqah (lodge) by the Ishqiyyah Sufi order. The mosque housed three important Islamic relics: a collection of very early Qurʾans, the shajjara (geneology) of the sheikhs (spiritual leaders) of the Ishqiyyah order, and the khirqah (cloak) of the Prophet Muhammad. Even though these relics are no longer kept in Langar Ota, the mosque and the mausoleum of Sheikh Muhammad Sadiq are still important centers for pilgrimage. More than 1,000 pilgrims per month visit the mausoleum and mosque of Langar Ota
