\nNarrated Ibn `Umar:\n \n\nI heard Allah's Messenger (ﷺ) saying, "When you see the crescent (of the month of Ramadan), start fasting, \nand when you see the crescent (of the month of Shawwal), stop fasting; and if the sky is overcast (and \nyou can't see it) then regard the month of Ramadan as of 30 days."\n

حَدَّثَنَا يَحْيَى بْنُ بُكَيْرٍ، قَالَ حَدَّثَنِي اللَّيْثُ، عَنْ عُقَيْلٍ، عَنِ ابْنِ شِهَابٍ، قَالَ أَخْبَرَنِي سَالِمٌ، أَنَّ ابْنَ عُمَرَ ـ رضى الله عنهما ـ قَالَ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ ‏\n"‏ إِذَا رَأَيْتُمُوهُ فَصُومُوا، وَإِذَا رَأَيْتُمُوهُ فَأَفْطِرُوا، فَإِنْ غُمَّ عَلَيْكُمْ فَاقْدُرُوا لَهُ ‏"‏‏.‏ وَقَالَ غَيْرُهُ عَنِ اللَّيْثِ حَدَّثَنِي عُقَيْلٌ وَيُونُسُ لِهِلاَلِ رَمَضَانَ‏.‏
