حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا غُنْدَرٌ، حَدَّثَنَا شُعْبَةُ، قَالَ سَمِعْتُ قَتَادَةَ، عَنْ أَنَسِ بْنِ مَالِكٍ، عَنْ أُسَيْدِ بْنِ حُضَيْرٍ، أَنَّ رَجُلاً، مِنَ الأَنْصَارِ قَالَ يَا رَسُولَ اللَّهِ، أَلاَ تَسْتَعْمِلُنِي كَمَا اسْتَعْمَلْتَ فُلاَنًا قَالَ " سَتَلْقَوْنَ بَعْدِي أَثَرَةً فَاصْبِرُوا حَتَّى تَلْقَوْنِي عَلَى الْحَوْضِ ".
