حَدَّثَنَا حَفْصُ بْنُ عُمَرَ، وَمُسْلِمُ بْنُ إِبْرَاهِيمَ، - الْمَعْنَى قَرِيبٌ - قَالاَ حَدَّثَنَا شُعْبَةُ، عَنْ سِمَاكِ بْنِ حَرْبٍ، عَنْ أَبِي صَفْوَانَ بْنِ عُمَيْرَةَ، قَالَ أَتَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم بِمَكَّةَ قَبْلَ أَنْ يُهَاجِرَ بِهَذَا الْحَدِيثِ وَلَمْ يَذْكُرْ يَزِنُ بِالأَجْرِ . قَالَ أَبُو دَاوُدَ رَوَاهُ قَيْسٌ كَمَا قَالَ سُفْيَانُ وَالْقَوْلُ قَوْلُ سُفْيَانَ .
