WE RELATE FROM the Ṣaḥīḥ of Muslim from Umm Salamah 
, who reported: “The Messenger of Allah 
said: ‘If you are with a sick person or a person in the agony of death then speak [only] good, for the angels say Āmīn to what you say.’ When Abū Salamah 
passed away I came to the Messenger of Allah and said: ‘O Messenger of Allah, Abū Salamah has passed away.’ He said: ‘Say: O Allah, forgive me and him, and give me good after him.’ I say that Allah gave me better than him: Muḥammad .” [1].Such is the version in the Ṣaḥīḥ of Muslim. At-Tirmidhī’s version has: “when you visit the sick or the dead. . .”, there being doubt [from the narrator]. The Sunan of Abū Dāwūd and others read “the dead” without ambiguity, unequivocally.

We relate in the Sunans of Abū Dāwūd and Ibn Mājah from Mu‘aqqal ibn Yasār al-Anṣārī , who reported that the Messenger of Allah said: “Recite Yā Sīn over your deceased.” [2].I say that the isnād is weak as there are two unknown transmitters in the isnād although Abū Dāwūd did not consider it weak.
