أَخْبَرَنَا مُحَمَّدُ بْنُ عَبْدِ الأَعْلَى، قَالَ حَدَّثَنَا خَالِدٌ، قَالَ حَدَّثَنَا شُعْبَةُ، عَنْ قَتَادَةَ، قَالَ سَمِعْتُ أَنَسًا، يُحَدِّثُ عَنْ أُسَيْدِ بْنِ حُضَيْرٍ، أَنَّ رَجُلاً، مِنَ الأَنْصَارِ جَاءَ رَسُولَ اللَّهِ صلى الله عليه وسلم فَقَالَ أَلاَ تَسْتَعْمِلْنِي كَمَا اسْتَعْمَلْتَ فُلاَنًا قَالَ ‏
"‏ إِنَّكُمْ سَتَلْقَوْنَ بَعْدِي أَثَرَةً فَاصْبِرُوا حَتَّى تَلْقَوْنِي عَلَى الْحَوْضِ ‏"‏‏.‏
