"If forty believers intercede for a believer, Allāh will accept their intercession for him." Narrated by Ibn Mājah (1/453) from Bakr ibn Sulaym who said: Ḥumayd ibn Ziyād al-Kharrāṭ narrated to me from Kurayb, the freed slave of ʿAbd Allāh ibn ʿAbbās, who said: "A son of ʿAbd Allāh ibn ʿAbbās passed away, and he said to me: O Kurayb! Go and see if anyone has gathered for my son. I said: Yes. He said: Woe to you, how many do you see... forty? I said: No, rather more. He said: Then take my son out, for I bear witness that I heard the Messenger of Allāh (ṣallá Allāhu ʿalayhi wa-sallam) say: [and he mentioned it]." I said: This isnād is weak, its flaw is Bakr, who was mentioned by al-Dhahabī in "al-Mughnī", and he said: "Ibn ʿAdī said: He narrates what no one else follows him in, and he is weak." I said: And he was contradicted in his isnād by ʿAbd Allāh ibn Wahb who said: Abū Ṣakhr (who is Ḥumayd ibn Ziyād al-Kharrāṭ) narrated to me from Sharīk ibn ʿAbd Allāh ibn Abī Namr from Kurayb, the freed slave of Ibn ʿAbbās, with a similar narration, and the wording of the elevated part is: "If a Muslim man dies, and forty men who do not associate anything with Allāh stand over his funeral, Allāh will accept their intercession for him." Narrated by Muslim (3/53), Abū Dāwūd (2/64), al-Bayhaqī (4/30), and Aḥmad (1/277-278).

Narrated by Abū al-Ṭayyib al-Ḥūrānī in "His Part" (70/1), Abū Nuʿaym in "al-Ḥilyah" (2/196), and al-Daylamī (4/8-9) from Muḥammad ibn ʿAbd Allāh ibn Abī Ḥammād al-Qaṭṭān who narrated to us
