Chapter 15 · The Book of Fastingحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا مُحَمَّدُ بْنُ بِشْرٍ الْعَبْدِيُّ، حَدَّثَنَا عُبَيْدُ اللهِ بْنُ عُمَرَ، عَنْ أَبِي الزِّنَادِ، عَنِ الْأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللهُ عَنْهُ، قَالَ: ذَكَرَ رَسُولُ اللهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ الْهِلَالَ فَقَالَ: «إِذَا رَأَيْتُمُوهُ فَصُومُوا، وَإِذَا رَأَيْتُمُوهُ فَأَفْطِرُوا، فَإِنْ أُغْمِيَ عَلَيْكُمْ فَعُدُّوا ثَلَاثِينَ».

The Messenger of Allah (may peace he upon him) made a mention of the new moon and (in this connection) said: Observe fast when you see it (the new moon) and break fast when you see it (the new moon of Shawwal), but when (the actual position of the month is) concealed from you (on account of cloudy sky), then count thirty days.
