Sahl,” or “Ṣadaqah ibn [Abū] Sahl”—the latter is perhaps closer to the correct reading. This is how I corrected it in my new book, Taysīr al-Intifāʿ. Allah knows best.

Among the errors is the statement of Dr. Muḥammad al-Bukhārī in his annotation on al-Duʿāʾ. After attributing the hadith to Aḥmad, he said:

“And he said: Saʿīd ibn al-Rabīʿ narrated to us ...”

But this is from the narration of his son ʿAbd Allāh, so it appears that his mention was inadvertently omitted from his pen.

Moreover, this hadith was narrated from Yūsuf ibn ʿAbd Allāh ibn Salām through another chain and with different wording, so its status must be clarified.

Imām Aḥmad said (6/442–443): Muḥammad ibn Bakr narrated to us; he said: Maymūn—meaning Abū Muḥammad al-Murāʾī al-Tamīmī—narrated to us; he said: Yaḥyā ibn Abī Kathīr narrated to us from Yūsuf ibn ʿAbd Allāh ibn Salām, who said:

“I kept company with Abū al-Dardāʾ in order to learn from him. When death approached him, he said, ‘Inform the people of my death.’ So I informed the people of his death. Then I came, and the house and everything around it were filled [with people]. He said, ‘Take me out.’ So we took him out. He said, ‘Seat me.’ So we seated him. Then he said, ‘O people, I heard the Messenger of Allah, peace and blessings be upon him, say:

“Whoever performs minor ablution and performs it thoroughly, then prays two rakʿahs and completes them, Allah will grant him what he asks for, either immediately or later.’”

Abū al-Dardāʾ said: “O people, beware of turning about during prayer, for there is no prayer for one who turns about. If you are overcome by it during voluntary prayer, then do not let it overcome you during the obligatory prayer.”
