The Shah-Cher­akh Mosque is a mau­soleum in which the graves of Ahmed and Mohammed, the sons of Mus­sa al-Kadim and the broth­ers of Imam Reza, are locat­ed. In fact, they are direct descen­dants of the Prophet. There­fore, it is a very spir­i­tu­al and reli­gious place with an end­less num­ber of pil­grims from all over the world.
