—the one who, in his day in Baghdad, was universally acclaimed for his asceticism, scrupulousness, frequent recitation, and mastery of jurisprudence and hadith. He had recited the Qur’an under Abū Ḥafṣ al-Kattānī and studied the variant readings, yet he never granted an isnād to anyone who read those readings with him.
Hibat Allāh ibn al-Mujallī states in The Merits of al-Qazwīnī: “He was, so to speak, a point of unanimous agreement in righteousness, one of those toward whom hearts incline.” He then told me, “Aḥmad ibn Muḥammad al-Amīn related:
