حَدَّثَنَا أَحْمَدُ بْنُ الْمِقْدَامِ، حَدَّثَنَا الْمُعْتَمِرُ بْنُ سُلَيْمَانَ، سَمِعْتُ أَبِي يُحَدِّثُ، عَنْ قَتَادَةَ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ كَانَتْ عَامَّةُ وَصِيَّةِ رَسُولِ اللَّهِ صلى الله عليه وسلم حِينَ حَضَرَتْهُ الْوَفَاةُ وَهُوَ يُغَرْغِرُ بِنَفْسِهِ ‏"‏ الصَّلاَةَ وَمَا مَلَكَتْ أَيْمَانُكُمْ ‏"‏ ‏.‏
