أَخْبَرَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، عَنْ يَحْيَى، عَنِ الأَعْمَشِ، قَالَ حَدَّثَنِي شَقِيقٌ، عَنْ أُمِّ سَلَمَةَ، قَالَتْ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ " إِذَا حَضَرْتُمُ الْمَرِيضَ فَقُولُوا خَيْرًا فَإِنَّ الْمَلاَئِكَةَ يُؤَمِّنُونَ عَلَى مَا تَقُولُونَ " . فَلَمَّا مَاتَ أَبُو سَلَمَةَ قُلْتُ يَا رَسُولَ اللَّهِ كَيْفَ أَقُولُ قَالَ " قُولِي اللَّهُمَّ اغْفِرْ لَنَا وَلَهُ وَأَعْقِبْنِي مِنْهُ عُقْبَى حَسَنَةً " . فَأَعْقَبَنِي اللَّهُ عَزَّ وَجَلَّ مِنْهُ مُحَمَّدًا صلى الله عليه وسلم .
It was narrated that Umm Salamah said: "I heard the Messenger of Allah say: 'When you see the dead, say something good, for the angels say Amin to whatever you say; When Abu Salamah died, I said: 'O Messenger of Allah, what should I say?' He said: 'Say" Allahummaghfirlanaa wa lahu wa a 'qibni minhu 'uqbai hasanah (O Allah, forgive us and him, and compensate me well for this loss.)"' Then Allah, the Mighty and Sublime, compensated me with Muhammad." Translation Not Available
