[Machine] When it was the night on which the Prophet ﷺ received the first revelation of the Qur'an, he performed the Maghrib prayer, and then said, "Indeed, this month is written upon you a month of fasting, and Allah has not prescribed the optional night prayer upon you. So whoever is able to establish it should do so, for it is from the extra good deeds which Allah has prescribed for you. And whoever is not able to do so, let him sleep on his bed and not say, 'I fasted and prayed at night as so-and -so did.' Whoever fasts or prays at night, let him do it for the sake of Allah, and reduce idle talk and nonsense in the houses of Allah. And let each of you know that during the prayer you are waiting for, do not anticipate the beginning of the month from your own calculation or by sighting the moon. Fast when you see it and break the fast when you see it, but if you are unable to see it, then count Sha`ban as thirty days. And do not break the fast until the night is completely dark."  

كَانَ عُمَرُ ؓ إِذَا كَانَتِ اللَّيْلَةُ الَّتِي يُشَكُّ فِيهَا مِنْ رَمَضَانَ قَامَ حِينَ يُصَلِّي الْمَغْرِبَ ثُمَّ قَالَ إِنَّ هَذَا شَهْرٌ كَتَبَ اللهُ عَلَيْكُمْ صِيَامَهُ وَلَمْ يَكْتُبْ عَلَيْكُمْ قِيَامَهُ فَمَنِ اسْتَطَاعَ مِنْكُمْ أَنْ يَقُومَ فَلْيَقُمْ فَإِنَّهَا مِنْ نَوَافِلِ الْخَيْرِ الَّتِي أَمَرَ اللهُ ﷻ بِهَا وَمَنْ لَمْ يَسْتَطِعْ فَلْيَنَمْ عَلَى فِرَاشِهِ وَلَا يَقُلْ قَائِلٌ إِنْ صَامَ فُلَانٌ صُمْتُ وَإِنْ قَامَ فُلَانٌ قُمْتُ فَمَنْ صَامَ أَوْ قَامَ فَلْيَجْعَلْ ذَلِكَ لِلَّهِ ﷻ أَقِلُّوا اللَّغْوَ فِي بُيُوتِ اللهِ ﷻ وَلْيَعْلَمْ أَحَدُكُمْ أَنَّهُ فِي صَلَاةٍ مَا انْتَظَرَ الصَّلَاةَ أَلَا لَا يَتَقَدَّمَنَّ الشَّهْرَ مِنْكُمْ أَحَدٌ صُومُوا لِرُؤْيَتِهِ وَأَفْطِرُوا لِرُؤْيَتِهِ فَإِنْ غُمَّ عَلَيْكُمْ فَعُدُّوا شَعْبَانَ ثَلَاثِينَ ثُمَّ لَا تُفْطِرُوا حَتَّى يَغسِقَ اللَّيْلُ عَلَى الظِّرَابِ
