حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا يَزِيدُ بْنُ هَارُونَ، حَدَّثَنَا هَمَّامٌ، عَنْ قَتَادَةَ، عَنْ صَالِحٍ أَبِي الْخَلِيلِ، عَنْ سَفِينَةَ، عَنْ أُمِّ سَلَمَةَ، أَنَّ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ كَانَ يَقُولُ فِي مَرَضِهِ الَّذِي تُوُفِّيَ فِيهِ " الصَّلاَةَ وَمَا مَلَكَتْ أَيْمَانُكُمْ " . فَمَا زَالَ يَقُولُهَا حَتَّى مَا يَفِيضَ بِهَا لِسَانُهُ .
