وَحَدَّثَنِى إِسْحَاقُ بْنُ مَنْصُورٍ أَخْبَرَنَا حَبَّانُ بْنُ هِلاَلٍ حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ حَدَّثَنِى يَحْيَى بْنُ سَعِيدٍ وَرَبِيعَةُ الرَّأْىِ بْنُ أَبِى عَبْدِ الرَّحْمَنِ عَنْ يَزِيدَ مَوْلَى الْمُنْبَعِثِ عَنْ زَيْدِ بْنِ خَالِدٍ الْجُهَنِىِّ أَنَّ رَجُلاً سَأَلَ النَّبِىَّ -صلى الله عليه وسلم- عَنْ ضَالَّةِ الإِبِلِ. زَادَ رَبِيعَةُ فَغَضِبَ حَتَّى احْمَرَّتْ وَجْنَتَاهُ. وَاقْتَصَّ الْحَدِيثَ بِنَحْوِ حَدِيثِهِمْ وَزَادَ « فَإِنْ جَاءَ صَاحِبُهَا فَعَرَفَ عِفَاصَهَا وَعَدَدَهَا وَوِكَاءَهَا فَأَعْطِهَا إِيَّاهُ وَإِلاَّ فَهْىَ لَكَ ».
