“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).’”
