أَخْبَرَنَا أَبُو دَاوُدَ، قَالَ حَدَّثَنَا هَارُونُ، قَالَ حَدَّثَنَا عَلِيٌّ، - هُوَ ابْنُ الْمُبَارَكِ - قَالَ حَدَّثَنَا يَحْيَى، عَنْ أَبِي سَلَمَةَ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ الشَّهْرُ يَكُونُ تِسْعَةً وَعِشْرِينَ وَيَكُونُ ثَلاَثِينَ فَإِذَا رَأَيْتُمُوهُ فَصُومُوا وَإِذَا رَأَيْتُمُوهُ فَأَفْطِرُوا فَإِنْ غُمَّ عَلَيْكُمْ فَأَكْمِلُوا الْعِدَّةَ ‏"‏ ‏.‏
