text: Ibn Khallikan could find no report of Muslim's date of birth, or age at death, by any of the ḥuffāẓ (hadith masters), except their agreement that he was born after 200 AH (815/816). Ibn Khallikan cites Ibn al-Salah, who cites Ibn al-Bayyiʿ's Kitab ʿUlama al-Amsar, in the claim that Muslim was 55 years old when he died on 25 Rajab, 261 AH (May 875) and therefore his year of birth must have been 206 AH (821/822).
  Ibn al-Bayyiʿ reports that he was buried in Nasarabad, a suburb of Nishapur.
  According to scholars, he was of Arab origin. The nisbah of "al-Qushayri" signifies Muslim's belonging to the Arab tribe of Banu Qushayr, members of which migrated to the newly conquered Persian territory during the expansion of the Rashidun Caliphate. According to two scholars, Ibn al-Athīr and Ibn al-Salāh, he was actually an Arab member of that tribe of which his family had migrated to Persia nearly two centuries earlier following the conquest.
