I said to Ubayy ibn Kaʿb: What do you think, if the wives of the Prophet (ṣallá Allāhu ʿalayhi wa-sallam) passed away, would he not be allowed to marry? He replied: What would prevent him from that—sometimes Dāwūd said: What would make it forbidden for him? I said: His statement: "It is not lawful for you to marry women after this," and he said: Allāh only permitted him a certain type of women, saying: "O Prophet, We have made lawful to you your wives..." up to His saying: "if she gives herself to the Prophet..." Then it was said to him: "It is not lawful for you to marry women after this" [after this description]. It was recorded by al-Dārimī (2/153-154), Ibn Saʿd (8/196), al-Bukhārī in "al-Tārīkh" (2/1/360), Ibn Jarīr in "al-Tafsīr" (22/31), ʿAbd Allāh ibn Aḥmad in "Zawāʾid al-Musnad" (5/132), and al-Ḍiyāʾ al-Maqdisī in "al-Mukhtārah" (numbers 1171 and 1172). Al-Bukhārī mentioned it briefly in the biography of this Ziyād, naming his father as (ʿAbd Allāh); Ibn Abī Ḥātim also named him thus, and did not mention any narrator for him other than this Muḥammad ibn Abī Mūsá, nor any authentication or criticism; therefore, al-Ḥusaynī said in "Rijāl al-Musnad": "I do not know him." Al-Ḥāfiẓ confirmed this in "al-Taʿjīl." As for al-Haythamī, he said—after attributing it to ʿAbd Allāh ibn Aḥmad (7/93): "I saw in 'Thiqāt Ibn Ḥibbān': 'Ziyād, Abū Yaḥyá al-Anṣārī, narrates from Ibn ʿAbbās'; if it is him, then he is trustworthy, and it appears that it is him. And Muḥammad ibn Abī Mūsá was mentioned by Ibn Ḥibbān in (al-Thiqāt)." And I say: In "Thiqāt Ibn Ḥibbān" there are three with this name and lineage, one of them (5/376) is a Successor who narrates from Ibn ʿAbbās, and from him Abū Saʿd al-Baqqāl
