أَخْبَرَنَا مُحَمَّدُ بْنُ يَحْيَى بْنِ عَبْدِ اللَّهِ النَّيْسَابُورِيُّ، قَالَ حَدَّثَنَا سُلَيْمَانُ بْنُ دَاوُدَ، قَالَ حَدَّثَنَا إِبْرَاهِيمُ، عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏ "‏ إِذَا رَأَيْتُمُ الْهِلاَلَ فَصُومُوا وَإِذَا رَأَيْتُمُوهُ فَأَفْطِرُوا فَإِنْ غُمَّ عَلَيْكُمْ فَصُومُوا ثَلاَثِينَ يَوْمًا ‏"‏ ‏.‏
