عَنْ أَبِي سَعِيدٍ وَأَبِي هُرَيْرَةَ قَالَا: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «لَقِّنُوا مَوْتَاكُمْ لَا إِلَهَ إِلَّا اللَّهُ» . رَوَاهُ مُسْلِمٌ

Umm Salama reported God’s messenger as saying, “When you are with one who is ill or dying speak good words, for the angels say Amen to what you say.” Muslim transmitted it.
