Muslim ibn al-Hajjaj
In the year 864/250, he settled in Nishapur. It was in Nishapur that he met Muslim ibn al-Hajjaj. He would be considered his student, and eventually collector and organiser of hadith collection "Sahih Muslim" which is considered second only to that of al-Bukhari. Political problems led him to move to Khartank, a village near Samarkand where he died in the year 870/256.
