Hammām—namely Ibn Yaḥyā al-ʿAwadhī—contradicted him [in this], and he is trustworthy, for he narrated it from Qatādah as a mursal report, and this is closer to what is correct. However, it is authentically established from ʿĀʾishah with a sound chain of transmission that Ibn Umm Maktūm was appointed as deputy, as will come later.

It was also recorded by Aḥmad (12344), al-Bukhārī in al-Tārīkh al-Awsaṭ 1/54, Ibn al-Jārūd (310), Abū Yaʿlā (3110) and (3138), and Abū Nuʿaym in Ḥilyat al-Awliyāʾ 9/45 via the route of ʿAbd al-Raḥmān ibn Mahdī, and by Aḥmad (13000) via the route of Abū al-ʿAwāmm al-Qaṭṭān—both of them from ʿImrān ibn Dāwur al-Qaṭṭān, with the same chain. Some of them added in their narration: "And I saw him on the Day of al-Qādisiyyah, and with him was a black banner."

It was also recorded by Ibn Saʿd 4/205 from ʿAmr ibn ʿĀṣim al-Kilābī, from Hammām ibn Yaḥyā al-ʿAwadhī, from Qatādah, as a mursal report.

ʿImrān al-Qaṭṭān had combined the ḥadīth of Anas—in which he mentioned the presence of Ibn Umm Maktūm at al-Qādisiyyah—with the mursal ḥadīth of Qatādah, so sometimes he would narrate them together, and sometimes he would narrate the story of the appointment as deputy alone with the chain of the other ḥadīth about al-Qādisiyyah, as we have clarified in the preceding route under number (595). And Allāh, may He be exalted, knows best.

It is authentically established from ʿĀʾishah, may Allāh be pleased with her, in the collections of Ibn Ḥibbān (2134) and (2135), that the Prophet, peace and blessings be upon him, appointed Ibn Umm Maktūm as his deputy over Medina to lead the people in prayer.

The statement "twice" is not sound in this regard, because the scholars of biography mentioned that the Prophet, peace and blessings be upon him, used to appoint him as deputy in most of his campaigns. For Ibn Saʿd said in al-Ṭabaqāt 4/205: "The Messenger of Allāh, peace and blessings be upon him, used to appoint him over Medina to lead the people in prayer in most of the Messenger of Allāh's campaigns." And Khalīfah ibn Khayyāṭ said in his Tārīkh, p. 96, in listing the deputies of the Prophet, peace and blessings be upon him: "He appointed over Medina Ibn Umm Maktūm thirteen times during his campaigns: in the campaign of al-Abwāʾ, Buwāṭ, Dhī al-ʿUshayrah, his departure toward the region of Juḥaynah in pursuit of Kurz ibn Jābir, when he set out for Badr and then sent back Abū Lubābah and appointed him in his place, the campaign of al-Sawīq, Ghaṭafān, Uḥud, Ḥamrāʾ al-Asad, Najrān, Dhāt al-Riqāʿ, and the Farewell Pilgrimage."

As for what Ibn ʿAbd al-Barr said in al-Istīʿāb in the biography of Ibn Umm Maktūm: "As for Qatādah's narration from Anas that the Prophet, peace and blessings be upon him, appointed Ibn Umm Maktūm as deputy, it did not reach him what reached others"—as if he affirms this narration. Yet it has become clear to us that it is not sound from Anas, as we have explained, and this specific identification [of the number] is from Qatādah. And Allāh knows best.
