Sunan Ibn Majah 1447

It was narrated that Umm Salamah said:“The Messenger of Allah (ﷺ) said: ‘When you visit one who is sick or dying, say good things, for the angels say: Amin to whatever you say.’ When Abu Salamah died, I came to the Prophet (ﷺ) and said: ‘O Messenger of Allah! Abu Salamah has died.’ He said: ‘Say: “Allahummaghfir li wa lahu, wa a’qibni minhu ‘uqba hasanah (O Allah, forgive me and him, and compensate me with someone better than him).’” She said: ‘I said that, and Allah compensated me with someone better than him: Muhammad the Messenger of Allah (ﷺ).’”
