حَدَّثَنَا مَرْوَانُ بْنُ مُحَمَّدٍ ، عَنْ عَبْدِ اللَّهِ بْنِ وَهْبٍ ، عَنْ يَحْيَى بْنِ سَالِمٍ ، عَنْ أَبِي بَكْرِ بْنِ نَافِعٍ ، عَنْ أَبِيهِ ، عَنْ ابْنِ عُمَرَ رَضِيَ اللهِ عَنْهُ، قَالَ : تَرَاءَى النَّاسُ الْهِلَالَ، فَأَخْبَرْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَنِّي رَأَيْتُهُ، " فَصَامَوَأَمَرَ النَّاسَ بِالصِّيَامِ "
