“We entered upon Abū Ḥuṣayn to visit him while he was ill, and ʿĀṣim was with us. Abū Ḥuṣayn said to ʿĀṣim, ‘Do you remember a hadith that al-Qāsim ibn Mukhaymirah narrated to us?’ He said, ‘Yes. One day he narrated to us from ʿAbd Allāh ibn ʿAmr that the Messenger of Allah, peace and blessings be upon him, said...’ and he then mentioned it.” Abū Nuʿaym said: “No one narrated it from Abū Ḥuṣayn except Abū Bakr.”
I say: He is trustworthy and is among al-Bukhārī’s narrators. Although some criticism has been made of him, it is not detrimental. Ibn Ḥibbān defended him well and praised him in al-Thiqāt; and the narrators above him are trustworthy, among Muslim’s narrators. Thus, the chain of transmission is authentic.
ʿĀṣim ibn Abī al-Nujūd also narrated from Khaythamah ibn ʿAbd al-Raḥmān, from ʿAbd Allāh ibn ʿAmr ibn al-ʿĀṣ, that the Messenger of Allah, peace and blessings be upon him, said: “When a servant has been following a good course of worship and then falls ill, the angel assigned to him is told: ‘Record for him deeds like those he performed when he was free, until I either release him or take him to Me.’” Aḥmad narrated it (2/203), and its chain of transmission is good.
He then narrated it (2/159, 194, and 198), as did al-Dārimī (2/316), al-Ḥākim (1/348), and Abū Nuʿaym in al-Ḥilyah (7/249), through the route of al-Qāsim ibn Mukhaymirah, from ʿAbd Allāh ibn ʿAmr, attributed to the Prophet, with the wording: “Whenever a Muslim is afflicted with a bodily trial, Allah commands the guardian angels who watch over him: ‘Record for My servant, every day and night, the good that he used to do, so long as he is confined in My bonds.’” This is al-Ḥākim’s wording. He said: “Authentic according to the criteria of al-Bukhārī and Muslim,” and al-Dhahabī agreed with him. It is as they said.
1233 — “Follow the example of the two of my Companions who come after me: Abū Bakr and ʿUmar. Be guided by the guidance of ʿAmmār, and hold fast to the covenant of Ibn Masʿūd.”
It has been narrated from ʿAbd Allāh ibn Masʿūd, Ḥudhayfah ibn al-Yamān, Anas ibn Mālik, and ʿAbd Allāh ibn ʿUmar.
