Hadith 11
The Book of Fasting
It was narrated that Abu Hurairah said:
"The Messenger of Allah mentioned the crescent and said: 'When you see it, fast and when you see it, stop fasting, and if it is obscured from you (too cloudy), then count thirty days."'
أَخْبَرَنَا أَبُو بَكْرِ بْنُ عَلِيٍّ، صَاحِبُ حِمْصَ قَالَ حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، قَالَ حَدَّثَنَا مُحَمَّدُ بْنُ بِشْرٍ، قَالَ حَدَّثَنَا عُبَيْدُ اللَّهِ، عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، قَالَ ذَكَرَ رَسُولُ اللَّهِ صلى الله عليه وسلم الْهِلاَلَ فَقَالَ
إِذَا رَأَيْتُمُوهُ فَصُومُوا وَإِذَا رَأَيْتُمُوهُ فَأَفْطِرُوا فَإِنْ غُمَّ عَلَيْكُمْ فَعُدُّوا ثَلاَثِينَ
