He heard from ʿAbd Allah ibn Rifāʿah al-Faradī fourteen fascicles of the Khilʿiyyāt; the latter granted him an ijāzah, and he was the last of his pupils. He received no transmissions from anyone else.
Those who narrated from him include al-Ḍiyāʾ, Ibn Khalīl, al-Barzalī, Ibn al-Nābulusī, his son ʿAlī ibn Ṣabbāḥ, the preacher Muḥyī al-Dīn Ibn al-Ḥarastānī, Abū al-Yumn Ibn ʿAsākir, his cousin Abū al-Faḍl, the Arabic grammarian Jamāl al-Dīn Ibn Mālik, Abū al-Ḥusayn Ibn al-Yūnīnī, al-ʿIzz Ibn al-Farrāʾ, al-ʿIzz Ibn al-ʿImād, Muḥammad ibn Qaymaz al-Daqīqī, al-ʿImād ibn Saʿd, Muḥammad ibn Abī al-Dhikr, ʿAlī ibn Baqāʾ, Muḥammad ibn Sulṭān al-Ḥanafī, and many others—the last of them to die was Shihāb ibn Musharraf the cloth-merchant.
ʿUmar ibn al-Ḥājib said: “He was a trustworthy shaykh, dignified, generous to the people of hadith, and exceedingly humble.
“He told me that he could go six months without drinking water. I asked, ‘Did you give it up for some specific reason?’ He replied, ‘I simply feel no desire for it.’”
I read, in the hand of the ḥāfiẓ al-Ḍiyāʾ: “Our shaykh Abū Ṣādiq passed away and was carried to the Mountain on Friday, 16 Rajab 632 AH.” He added, “He was a righteous man; scarcely did I meet anyone who did not thank him and praise him—may Allah have mercy on him.”
