his Sunan—he counted him among his senior shaykhs—as did Ḥarb al-Karmānī, Abū Zurʿah, ʿAbd al-Karīm ibn al-Haytham al-ʿĀqūlī, ʿUthmān ibn Khurrāzād al-Anṭākī, Aḥmad ibn Dāwūd al-Makkī, Abū Bakr ibn Abī ʿĀṣim, Abū Muslim al-Kajjī, Muḥammad ibn Muḥammad ibn Ḥayyān al-Tammār, Abū Khalīfah al-Jumaḥī, and many others.
Al-Qawārīrī said, “Yaḥyā al-Qaṭṭān was not satisfied with ʿAmr ibn Marzūq in the matter of hadith.” (1)
Abū Zurʿah reported, “I heard Sulaymān ibn Ḥarb mention ʿAmr ibn Marzūq and say, ‘He produced what they did not possess, so they envied him.’” (2)
Saʿīd ibn Saʿd al-Bukhārī related: “I heard Muslim ibn Ibrāhīm say, ‘The books kept by Abū Dāwūd al-Ṭayālisī actually belonged to ʿAmr ibn Marzūq. ʿAmr was a man of jihad, undertaking naval expeditions, and when Abū Dāwūd died ʿAmr reclaimed his books.’” (3)
ʿAlī ibn al-Madīnī said, “They abandoned the hadith of the two Fahds and the two ʿAmrs,” meaning Fahd ibn ʿAwf, Fahd ibn Ḥayyān, ʿAmr ibn Ḥakkām, and ʿAmr ibn Marzūq. (4)
It was said that ʿAmr ibn Marzūq possessed three thousand hadiths narrated from Shuʿbah. (5)
Abū’l-Fatḥ al-Azdī remarked, “The audition of Abū Dāwūd and that of ʿAmr ibn Marzūq from Shuʿbah was one and the same, and Yaḥyā ibn Maʿīn used to extol ʿAmr and speak highly of him.”
