Al Nasafi Al Dai

Abu Abd Allah Muhammad ibn Ahmad al-Nasafi al-Nakhshabi, one of the authors of the Isma'ilis. ²

Ibn al-Nadim attributes to him the book "Unwan al-Din", the book "Usul al-Shar'", and the book "al-Da'wa al-Mutajjaba". ²

Ibn al-Nadim relates that he succeeded al-Marwazi in Khurasan, and brought Nasr ibn Ahmad into the call. He charged Nasr with al-Marwazi's blood-money, and claimed he would send it to the ruler of the Maghrib who held the imamate. Then he joined Nasr and fell ill; he regretted having answered al-Nasafi and made this known, and died. ³
