'Abdur-Rahman bin Zaid bin Al-Khattab addressed the people on the day concerning which there was doubt (as to whether the month had begun) and said: "I sat with the Companions of the Messenger of Allah and asked them, and they a narrated that the Messenger of Allah said: 'Fast when you see it and stop fasting when you see it, and perform the rites on that basis. If it is obscured, then complete thirty days, and if two witnesses testify then fast and stop fasting." (Using translation from Nasāʾī 2116)

أَلَا إِنِّي قَدْ جَالَسْتُ أَصْحَابَ رَسُولِ اللهِ ﷺ وَسَأَلْتُهُمْ أَلَا وَإِنَّهُمْ حَدَّثُونِي أَنَّ رَسُولَ اللهِ ﷺ قَالَ صُومُوا لِرُؤْيَتِهِ وَأَفْطِرُوا لِرُؤْيَتِهِ وَأَنْسِكُوا لَهَا فَإِنْ غُمَّ عَلَيْكُمْفَأَتِمُّوا ثَلَاثِينَ وَإِنْ شَهِدَ شَاهِدَانِ مُسْلِمَانِ فَصُومُوا وَأَفْطِرُوا

[Machine] Narrated by the Prophet (PBUH), he said: "Do not start the month (of Ramadan) by a day or two unless one of you sees the new moon. Fast when you see it and break your fast when you see it. If it is cloudy and you cannot see it, complete thirty days of the month and then break your fast."

عَنِ النَّبِيِّ ﷺ قَالَ لَا تَقَدَّمُوا الشَّهْرَ بِيَوْمٍ وَلَا بيَوْمَيْنِ إِلَّا أَنْ يُوَافِقَ أَحَدُكُمْ صَوْمًا كَانَ يَصُومُهُ صُومُوا لِرُؤْيَتِهِ وَأَفْطِرُوا لِرُؤْيَتِهِ فَإِنْ غُمَّ عَلَيْكُمْ فَأَتِمُّوا ثَلَاثِينَ يَوْمًا ثُمَّ أَفْطِرُوا

"the Messenger of Allah said: 'Fast when you see it and stop fasting when you see it, and if it is obscured from you (too cloudy), then count it as thirty (days). "' (Using translation from Nasāʾī 2117)

عَنْ رَسُولِ اللَّهِ ﷺ قَالَ «صُومُوا لِرُؤْيَتِهِ وَأَفْطِرُوا لِرُؤْيَتِهِ فَإِنْ غُمَّ عَلَيْكُمْ فَصُومُوا ثَلَاثِينَ»

"the Messenger of Allah said: 'Fast when you see it and stop fasting when you see it, and if it is obscured from you (too cloudy), then count it as thirty (days). "' (Using translation from Nasāʾī 2117)

قَالَ رَسُولُ اللَّهِ ﷺ «صُومُوا لِرُؤْيَتِهِ وَأَفْطِرُوا لِرُؤْيَتِهِ فَإِنْ غُمَّ عَلَيْكُمْ فَعُدُّوا ثَلَاثِينَ يَوْمًا ثُمَّ أَفْطِرُوا»

Observe fast on sighting it (the new moon) and break (fast) on sighting it (the new moon), but if the sky is cloudy for you, then complete the number (of thirty). (Using translation from Muslim 1081b)

قَالَ رَسُولُ اللهِ ﷺ صُومُوا لِرُؤْيَتِهِ وَأَفْطِرُوا لِرُؤْيَتِهِ فَإِنْ غُمَّ عَلَيْكُمْ فَصُومُوا ثَلَاثِينَ
