وَحَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ نُمَيْرٍ، حَدَّثَنَا عَبْدُ اللَّهِ، - يَعْنِي ابْنَ إِدْرِيسَ - قَالَ سَمِعْتُ حُصَيْنًا، عَنْ سَعْدِ بْنِ عُبَيْدَةَ، عَنِ الْبَرَاءِ بْنِ عَازِبٍ، عَنِ النَّبِيِّ صلى الله عليه وسلم . بِهَذَا الْحَدِيثِ غَيْرَ أَنَّ مَنْصُورًا أَتَمُّ حَدِيثًا وَزَادَ فِي حَدِيثِ حُصَيْنٍ " وَإِنْ أَصْبَحَ أَصَابَ خَيْرًا " .
