al-Wāsiṭī, ʿAbd Allāh ibn al-Haytham Dulbah, and ʿAbd Allāh ibn al-Rabīʿ al-Malṭī—the teacher of al-Muṭṭawīʿī—also recited the Qur’an to him.
Those who learned the ḥurūf (variant readings) from him were: Muḥammad ibn ʿAbd al-Raḥīm al-Iṣbahānī, Usāmah ibn Aḥmad, Ibn Khuzaymah, Ibn Jarīr, Muḥammad ibn al-Rabīʿ al-Jīzī, and others.
He was counted among the leading critics of narrators and the foremost scholars of Egypt in his day.
Yaḥyā ibn Ḥassān al-Tinnīsī said, “This Yunus of yours is a pillar among the pillars of Islam.” (1)
Al-Nasāʾī declared, “Trustworthy.”
Ibn Abī Ḥātim said, “I heard my father declare him reliable and hold him in high regard.” (2)
Abū Ḥātim also said, “I heard Abū al-Ṭāhir ibn al-Sarḥ urging people to learn from Yunus and magnifying his stature.”
ʿAlī ibn al-Ḥasan ibn Qudayd remarked, “He had committed ḥadith to memory.”
Al-Ṭaḥāwī said, “He was a man of sound intellect. ʿAlī ibn ʿAmr ibn Khālid narrated to me: I heard my father say that al-Shāfiʿī said, ‘O Abū al-Ḥasan, look at that first gate among the gates of the congregational mosque.’ I looked at it, and he said, ‘No one enters through that gate who possesses more intelligence than Yunus ibn ʿAbd al-Aʿlā.’” (3)
