Rashid al-Din
The main components of the foundation were a library, a hospice, a hospital, a khanqah, and a tomb with winter and summer mosques. The tomb was originally that of Rashid al-Din, built by his son Muhammed Ghiyath. However, due to what is believed to have been a conspiracy, Rashid al-Din was executed under the false pretext that he had poisoned Oljeitu Khan. This turn of events was further compounded by rumors that emerged during the reign of Miran Shah (1404-1407) that Rashid al-Din had been Jewish; consequently, his remains were exhumed from his tomb at the Rab'-e Rashidi and moved to a Jewish cemetery.
