الدارمي:١٣٧أَخْبَرَنَا أَبُو نُعَيْمٍ حَدَّثَنَا سُفْيَانُ عَنْ عَطَاءِ بْنِ السَّائِبِ قَالَ سَمِعْتُ عَبْدَ الرَّحْمَنِ بْنَ أَبِي لَيْلَى يَقُولُ لَقَدْ أَدْرَكْتُ فِي هَذَا الْمَسْجِدِ عِشْرِينَ وَمِائَةً مِنَ الْأَنْصَارِ «وَمَا مِنْهُمْ مِنْ أَحَدٍ يُحَدِّثُ بِحَدِيثٍ إِلَّا وَدَّ أَنَّ أَخَاهُ كَفَاهُ الْحَدِيثَ وَلَا يُسْأَلُ عَنْ فُتْيَا إِلَّا وَدَّ

أَنَّ أَخَاهُ كَفَاهُ الْفُتْيَا»
