I heard Messenger of Allah ﷺ saying, "When you see the crescent (of the month of Ramadan), start fasting, and when you see the crescent (of the month of Shawwal), stop fasting; and if the sky is overcast (and you can't see it) then regard the month of Ramadan as of 30 days."  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ إِذَا رَأَيْتُمُوهُ فَصُومُوا وَإِذَا رَأَيْتُمُوهُ فَأَفْطِرُوا فَإِنْ غُمَّ عَلَيْكُمْ فَاقْدُرُوا لَهُ وَقَالَ غَيْرُهُ عَنِ اللَّيْثِ حَدَّثَنِي عُقَيْلٌ وَيُونُسُ لِهِلاَلِ رَمَضَانَ  

The month (of Ramadan) may consist of twenty nine days; so when you see the new moon observe fast and when you see (the new moon again at the commencement of the month of Shawwal) then break It, and if the sky is cloudy for you, then calculate it (and complete thirty days).  

قَالَ رَسُولُ اللَّهِ ﷺ الشَّهْرُ تِسْعٌ وَعِشْرُونَ فَإِذَا رَأَيْتُمُ الْهِلاَلَ فَصُومُوا وَإِذَا رَأَيْتُمُوهُ فَأَفْطِرُوا فَإِنْ غُمَّ عَلَيْكُمْ فَاقْدِرُوا لَهُ  

When you see the new moon, observe fast, and when you see it (again) then break it, and if the sky is cloudy for you, then calculate it.  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ إِذَا رَأَيْتُمُوهُ فَصُومُوا وَإِذَا رَأَيْتُمُوهُ فَأَفْطِرُوا فَإِنْ غُمَّ عَلَيْكُمْ فَاقْدِرُوا لَهُ  

Whenever you sight the new moon (of the month of Ramadan) observe fast. and when you sight it (the new moon of Shawwal) break it, and if the sky is cloudy for you, then observe fast for thirty days.  

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا رَأَيْتُمُ الْهِلاَلَ فَصُومُوا وَإِذَا رَأَيْتُمُوهُ فَأَفْطِرُوا فَإِنْ غُمَّ عَلَيْكُمْ فَصُومُوا ثَلاَثِينَ يَوْمًا  

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.  

ذَكَرَ رَسُولُ اللَّهِ ﷺ الْهِلاَلَ فَقَالَ إِذَا رَأَيْتُمُوهُ فَصُومُوا وَإِذَا رَأَيْتُمُوهُ فَأَفْطِرُوا فَإِنْ أُغْمِيَ عَلَيْكُمْ فَعُدُّوا ثَلاَثِينَ  

"When you see the crescent then fast, and when you crescent then fast, and when you see it, stop fasting. If it is obscured from you (too cloudy), then fast thirty days."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِذَا رَأَيْتُمُ الْهِلاَلَ فَصُومُوا وَإِذَا رَأَيْتُمُوهُ فَأَفْطِرُوا فَإِنْ غُمَّ عَلَيْكُمْ فَصُومُوا ثَلاَثِينَ يَوْمًا  

" I heard the messenger of Allah say: 'When you see the crescent then fast, and when you see it, then stop fasting, and if it is obscured from you (too cloudy), then work it out (fro the beginning of the month, to complete thirty days)"'  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ إِذَا رَأَيْتُمُ الْهِلاَلَ فَصُومُوا وَإِذَا رَأَيْتُمُوهُ فَأَفْطِرُوا فَإِنْ غُمَّ عَلَيْكُمْ فَاقْدُرُوا لَهُ  

"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."'  

ذَكَرَ رَسُولُ اللَّهِ ﷺ الْهِلاَلَ فَقَالَ إِذَا رَأَيْتُمُوهُ فَصُومُوا وَإِذَا رَأَيْتُمُوهُ فَأَفْطِرُوا فَإِنْ غُمَّ عَلَيْكُمْ فَعُدُّوا ثَلاَثِينَ  

" I am surprised at those who anticipate the moth, when the Messenger of Allah said: 'When you see the new crescent then fast, and when you see it, then stop fasting, and if it is obscured from you (too cloudy), then complete thirty days.  

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا رَأَيْتُمُ الْهِلاَلَ فَصُومُوا وَإِذَا رَأَيْتُمُوهُ فَأَفْطِرُوا فَإِنْ غُمَّ عَلَيْكُمْ فَأَكْمِلُوا الْعِدَّةَ ثَلاَثِينَ  

‘When you see the new crescent, fast, and when you see it, stop fasting. If it is cloudy then calculate it (as thirty days).” Ibn ‘Umar used to fast one day before the new crescent was seen.  

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا رَأَيْتُمُ الْهِلاَلَ فَصُومُوا وَإِذَا رَأَيْتُمُوهُ فَأَفْطِرُوا فَإِنْ غُمَّ عَلَيْكُمْ فَاقْدُرُوا لَهُ وَكَانَ ابْنُ عُمَرَ يَصُومُ قَبْلَ الْهِلاَلِ بِيَوْمٍ  

“When you see the new crescent then fast, and when you see it then stop fasting. If it is cloudy then fast thirty days.”  

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا رَأَيْتُمُ الْهِلاَلَ فَصُومُوا وَإِذَا رَأَيْتُمُوهُ فَأَفْطِرُوا فَإِنْ غُمَّ عَلَيْكُمْ فَصُومُوا ثَلاَثِينَ يَوْمًا

"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."' (Using translation from Nasāʾī 2123)

[Machine] The Messenger of Allah ﷺ said: "Indeed, Allah, the Blessed and Exalted, has made the sighting of the moon as a means to determine the times (for fasting and breaking the fast). So, when you see it, fast, and when you see it again, break your fast. But if it is cloudy and you are unable to see it, then complete thirty days. This narration is from sources other than Ibn Umar, and it is established from Abu Hurairah from the Prophet ﷺ regarding this matter."  

قَالَ رَسُولُ اللهِ ﷺ إِنَّ اللهَ تَبَارَكَ وَتَعَالَى جَعَلَ الْأَهِلَّةَ مَوَاقِيتَ فَإِذَا رَأَيْتُمُوهُ فَصُومُوا وَإِذَا رَأَيْتُمُوهُ فَأَفْطِرُوا فَإِنْ غُمَّ عَلَيْكُمْ فَاقْدُرُوا لَهُ أَتِمُّوهُ ثَلَاثِينَ وَمِنْهَا عَنْ غَيْرِ ابْنِ عُمَرَ الرِّوَايَاتُ الثَّابِتَاتُ عَنْ أَبِي هُرَيْرَةَ عَنِ النَّبِيِّ ﷺ فِي هَذَا الْبَابِ

"إِنَّ الله ﷻ جَعَلَ هَذِهِ الأهِلَّةَ مَوَاقيتَ؛ فَإِذَا رَأَيتُمُوهُ، فَصُومُوا، وإذا رَأيتُمُوُهُ فَأَفْطِرُوا فَإِنْ غُمَّ عَلَيكُم فَعُدُّوا ثَلَاثِين".
