مسلم:٩٨٩cحَدَّثَنَا يَحْيَى بْنُ يَحْيَى أَخْبَرَنَا هُشَيْمٌ ح وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ حَدَّثَنَا حَفْصُ بْنُ غِيَاثٍ وَأَبُو خَالِدٍ الأَحْمَرُ ح وَحَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى

حَدَّثَنَا عَبْدُ الْوَهَّابِ وَابْنُ أَبِي عَدِيٍّ وَعَبْدُ الأَعْلَى كُلُّهُمْ عَنْ دَاوُدَ ح وَحَدَّثَنِي زُهَيْرُ بْنُ حَرْبٍ وَاللَّفْظُ لَهُ قَالَ حَدَّثَنَا إِسْمَاعِيلُ بْنُ إِبْرَاهِيمَ أَخْبَرَنَا دَاوُدُ عَنِ الشَّعْبِيِّ عَنْ جَرِيرِ بْنِ عَبْدِ اللَّهِ قَالَ قَالَ رَسُولُ اللَّهِ ﷺ إِذَا أَتَاكُمُ الْمُصَدِّقُ فَلْيَصْدُرْ عَنْكُمْ وَهُوَ عَنْكُمْ رَاضٍ
