It was recorded by al-Bukhārī (1/357/247), Muslim (8/77), Abū Dāwūd (5046-5047), al-Tirmidhī (3569) who authenticated it, al-Nasāʾī (781 and 782), Ibn Ḥibbān (5511), and al-Ṭabarānī in "al-Duʿāʾ" (2/905/245), as well as Aḥmad (4/293) and al-Bayhaqī in "Shuʿab al-Īmān" (4/173/4704) through various chains from Manṣūr with it. It was also recorded by Muslim, al-Nasāʾī (783-785), Ibn Abī Shaybah (9/73/6577 and 10/246/9345), and Aḥmad (4/246) through various chains from Saʿd ibn ʿUbaydah with a similar narration.

However, Sufyān was uncertain in the text of the ḥadīth whether it was his (ṣallá Allāhu ʿalayhi wa-sallam) own practice to say it at his resting place, or if he commanded others to do so. Both aspects are supported by narrations from Abū Isḥāq through Sufyān and others from him, and from others, and here is the clarification: Firstly, from Sufyān ibn ʿUyaynah from him. It was recorded by al-Tirmidhī (3391), al-Ruyānī in "Musnad" (folio 84/2-85/1), and al-Ṭabarānī in "al-Duʿāʾ" (2/903/241) through various chains from him with the wording of command, the first with the wording:
