Abū Zurʿah said, “I heard Aḥmad ibn Ḥanbal—when someone told him that ʿAlī ibn al-Madīnī had deemed ʿAmr weak—reply, ‘I do not know what ʿAlī is talking about; ʿAmr is a righteous man.’ (1)

ʿAbd Allāh ibn Muḥammad ibn al-Faḍl al-Asadī related: “Aḥmad ibn Ḥanbal said to his son Ṣāliḥ when the latter returned from Basra, ‘Why did you not write down hadith from ʿAmr ibn Marzūq?’ He answered, ‘I was forbidden.’ Aḥmad responded, ‘ʿAffān used to consider him reliable—and who is it that ʿAffān would approve of?! ʿAmr was a man of battle and virtue.’ (2)(3)

Muḥammad ibn ʿĪsā ibn Abī Qimāsh said, “I asked Yaḥyā ibn Maʿīn about ʿAmr ibn Marzūq, and he replied, ‘Trustworthy, reliable; a man of jihad, Qur’an, and merit,’ and he praised him profusely. (4)

Abū Ḥātim stated, “He was trustworthy, one of the devoted worshippers; among Shuʿbah’s students we did not find anyone whose hadith was better than his.” (5)

ʿAbd Allāh ibn ʿAdī reported: “I heard Aḥmad ibn Muḥammad ibn Khālid say, ‘In Basra there was no gathering larger than that of ʿAmr ibn Marzūq—may Allah have mercy on him; it numbered ten thousand people.’ (6)

Al-Nasāʾī, in al-Kunā, said: “Al-Ḥasan ibn Aḥmad ibn Ḥabīb informed us; Bundār narrated: I heard ʿAmr ibn Marzūq—he was asked, ‘Did you marry a thousand women?’—and he replied, ‘Or even more than a thousand women.’” (7)
