(1) Recorded by al-Bukhārī (5050). (2) Recorded by Ahmad (627), Abū Dāwūd (229), al-Tirmidhī (146), al-Nasā’ī in al-Mujtabā (265, 266) and al-Kubrā (257, 258), Ibn Mājah (594), Ibn Khuzayma (208), Ibn Hibbān (799, 800), al-Dāraqutnī (425, 429), al-Hākim (4:107), and al-Bayhaqī (1:88), through Shu‘ba, from ‘Amr ibn Murra, from ‘Abd Allāh ibn Salima, from ‘Alī ibn Abī Tālib, as a marfū‘ report (attributed to the Prophet). Its transmission hinges on ‘Abd Allāh ibn Salima. Al-Bukhārī stated in al-Tārīkh al-Kabīr (5:99): “Abū Dāwūd (al-Tayālisī) reported from Shu‘ba, from ‘Amr ibn Murra: ‘Abd Allāh used to narrate to us; we recognized some of his reports and found others objectionable. He had grown old.’” Al-Bukhārī then said: “He is not corroborated in this report.” For this reason, al-Shāfi‘ī and al-Bayhaqī regarded it as weak, as noted in Ma‘rifat al-Sunan (1:323–324). Al-Albānī also graded the hadith weak and discussed it in detail in Da‘īf Abī Dāwūd—al-Umm (1:79–85) and Irwā’ al-Ghalīl (485). The correct version is mawqūf (attributed to ‘Alī ibn Abī Tālib himself), recorded from him through several chains by ‘Abd al-Razzāq (1306, 1321) and Ibn Abī Shayba (1092, 1097, 1119). Muslim (373) recorded a report from ‘Ā’isha that the Prophet (peace and blessings be upon him) used to remember Allah at all times. Al-Bukhārī also cited it without its chain of transmission in his Sahīh, before hadiths 305 and 634, using an affirmative form of attribution.
