Ishāq bin Ibrāhīm al-Hanthalī narrated to us, he said, I heard one of the companions of Abd Allah say, Ibn al-Mubārak said: ‘What an excellent man is Baqiyyah, if it were not for the fact that he would provide a nickname for the birth name, and he would provide the birth name for a nickname. For a long time he would narrated to us on authority of Abī Sa’īd al-Wuhāthī, then when we investigated he was Abd ul-Quddūs ’.
