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.’”

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَعَلِيُّ بْنُ مُحَمَّدٍ، قَالاَ حَدَّثَنَا أَبُو مُعَاوِيَةَ، عَنِ الأَعْمَشِ، عَنْ شَقِيقٍ، عَنْ أُمِّ سَلَمَةَ، قَالَتْ قَالَ رَسُولُ اللَّهِ ﷺ " إِذَا حَضَرْتُمُ الْمَرِيضَ أَوِ الْمَيِّتَ فَقُولُوا خَيْرًا فَإِنَّ الْمَلاَئِكَةَ يُؤَمِّنُونَ عَلَى مَا تَقُولُونَ " . فَلَمَّا مَاتَ أَبُو سَلَمَةَ أَتَيْتُ النَّبِيَّ ﷺ فَقُلْتُ يَا رَسُولَ اللَّهِ إِنَّ أَبَا سَلَمَةَ قَدْ مَاتَ . قَالَ " قُولِي اللَّهُمَّ اغْفِرْ لِي وَلَهُ وَأَعْقِبْنِي مِنْهُ عُقْبَى حَسَنَةً " . قَالَتْ فَفَعَلْتُ فَأَعْقَبَنِي اللَّهُ مَنْ هُوَ خَيْرٌ مِنْهُ . مُحَمَّدٌ رَسُولُ اللَّهِ ﷺ .
