Once a person asked Messenger of Allah ﷺ ﷺ about the night prayer. Allah's Apostle ﷺ replied, "The night prayer is offered as two Rakʿat followed by two Rakʿat and so on and if anyone is afraid of the approaching dawn (Fajr prayer) he should pray one Rakʿah and this will be a Witr for all the Rakʿat which he has prayed before."  

أَنَّ رَجُلاً سَأَلَ رَسُولَ اللَّهِ ﷺ عَنْ صَلاَةِ اللَّيْلِ فَقَالَ رَسُولُ اللَّهِ ﷺ صَلاَةُ اللَّيْلِ مَثْنَى مَثْنَى فَإِذَا خَشِيَ أَحَدُكُمُ الصُّبْحَ صَلَّى رَكْعَةً وَاحِدَةً تُوتِرُ لَهُ مَا قَدْ صَلَّى  

Ibn ʿUmar said, "While the Prophet ﷺ was on the pulpit, a man asked him how to offer the night prayers. He replied, 'Pray two rakʿat at a time and then two and then two and so on, and if you are afraid of the dawn (the approach of the time of the Fajr prayer) pray one rakʿa and that will be the witr for all the rakʿat which you have offered." Ibn ʿUmar said, "The last rakʿat of the night prayer should be odd, for the Prophet ﷺ ordered it to be so.  

سَأَلَ رَجُلٌ النَّبِيَّ ﷺ وَهْوَ عَلَى الْمِنْبَرِ مَا تَرَى فِي صَلاَةِ اللَّيْلِ قَالَ مَثْنَى مَثْنَى فَإِذَا خَشِيَ الصُّبْحَ صَلَّى وَاحِدَةً فَأَوْتَرَتْ لَهُ مَا صَلَّى وَإِنَّهُ كَانَ يَقُولُ اجْعَلُوا آخِرَ صَلاَتِكُمْ وِتْرًا فَإِنَّ النَّبِيَّ ﷺ أَمَرَ بِهِ  

Prayer during the night should consist of pairs of rak'ahs, but if one of you fears morning is near, he should pray one rak'ah which will make his prayer an odd number for him.  

أَنَّ رَجُلاً سَأَلَ رَسُولَ اللَّهِ ﷺ عَنْ صَلاَةِ اللَّيْلِ فَقَالَ رَسُولُ اللَّهِ ﷺ صَلاَةُ اللَّيْلِ مَثْنَى مَثْنَى فَإِذَا خَشِيَ أَحَدُكُمُ الصُّبْحَ صَلَّى رَكْعَةً وَاحِدَةً تُوتِرُ لَهُ مَا قَدْ صَلَّى  

A man asked the Messenger of Allah ﷺ about prayer at night and the Messenger of Allah ﷺ said: "Prayer at night is two by two, then if one of you fears that dawn will break, pray one rak'ah to make the total number that he prayed odd."  

أَنَّ رَجُلاً سَأَلَ رَسُولَ اللَّهِ ﷺ عَنْ صَلاَةِ اللَّيْلِ فَقَالَ رَسُولُ اللَّهِ ﷺ صَلاَةُ اللَّيْلِ مَثْنَى مَثْنَى فَإِذَا خَشِيَ أَحَدُكُمُ الصُّبْحَ صَلَّى رَكْعَةً وَاحِدَةً تُوتِرُ لَهُ مَا قَدْ صَلَّى

Yahya related to me from Malik from Nafi and Abdullah ibn Umar that a man asked the Messenger of Allah ﷺ about night prayers. The Messenger of Allah ﷺ said, "Night prayers are two by two, and when you are afraid that dawn is approaching, pray one raka to make what you have prayed odd."  

أَنَّ رَجُلاً سَأَلَ رَسُولَ اللَّهِ ﷺ عَنْ صَلاَةِ اللَّيْلِ فَقَالَ رَسُولُ اللَّهِ ﷺ صَلاَةُ اللَّيْلِ مَثْنَى مَثْنَى فَإِذَا خَشِيَ أَحَدُكُمُ الصُّبْحَ صَلَّى رَكْعَةً وَاحِدَةً تُوتِرُ لَهُ مَا قَدْ صَلَّى  

[Machine] A man asked the Messenger of Allah ﷺ while he was on the pulpit about the night prayer. He replied, "It is to be performed in pairs." And if one of you fears that he will not wake up until morning, he should pray Witr (the odd-numbered prayer that is performed after Isha prayer)."  

سَأَلَ رَجُلٌ رَسُولَ اللهِ ﷺ وَهُوَ عَلَى الْمِنْبَرِ عَنْ صَلَاةِ اللَّيْلِ قَالَ مَثْنَى مَثْنَى فَإِذَا خَشِيَ أَحَدُكُمْ أَنْ يُصْبِحَ صَلَّى وَاحِدَةً فَأَوْتَرَتْ لَهُ مَا صَلَّى  

[Machine] A man called the Messenger of Allah ﷺ and said, "O Messenger of Allah, how do you command us to pray during the night?" He replied, "Each of you should pray two units of prayer, then when dawn approaches, pray one unit of prayer. That will complete what he has prayed."  

نَادَى رَجُلٌ رَسُولَ اللهِ ﷺ قَالَ يَا رَسُولَ اللهِ كَيْفَ تَأْمُرُنَا نُصَلِّي مِنَ اللَّيْلِ؟ قَالَ يُصَلِّي أَحَدُكُمْ مَثْنَى مَثْنَى فَإِذَا خَشِيَ الصُّبْحَ يُصَلِّي وَاحِدَةً فَأَوْتَرَتْ لَهُ مَا قَدْ صَلَّى

(Using translation from Abū Dāʾūd 1326)   

سَأَلَ رَجُلٌ رَسُولَ اللهِ ﷺ عَنْ صَلَاةِ اللَّيْلِ قَالَ يُصَلِّي أَحَدُكُمْ مَثْنَى مَثْنَى فَإِذَا خَشِيَ أَنْ يُصْبِحَصَلَّى رَكْعَةً تُوتِرُ لَهُ صَلَاتَهُ  

[Machine] The Messenger of Allah ﷺ was asked, "How should we pray at night?" He said, "Each of you should pray two rak'ahs and if morning approaches, then offer a single rak'ah (witr prayer)."  

سُئِلَ رَسُولُ اللَّهِ ﷺ كَيْفَ تَأْمُرُنَا أَنْ نُصَلِّيَ بِاللَّيْلِ؟ قَالَ «يُصَلِّي أَحَدُكُمْ مَثْنَى مَثْنَى فَإِذَا خَشِيَ الصُّبْحَ أَوْتَرَ بِرَكْعَةٍ»

نَادَى رَجُلٌ رَسُولَ اللَّهِ ﷺ فَقَالَ كَيْفَ تَأْمُرُنَا أَنْ نُصَلِّيَ مِنَ اللَّيْلِ؟ فَقَالَ «يُصَلِّي أَحَدُكُمْ مَثْنَى مَثْنَى فَإِذَا خَشِيَ الصُّبْحَ صَلَّى وَاحِدَةً أَوْتَرَتْ لَهُ مَا قَدْ صَلَّى مِنَ اللَّيْلِ»

أَنَّ رَجُلًا سَأَلَ رَسُولَ اللهِ ﷺ عَنْ صَلَاةِ اللَّيْلِ فَقَالَ رَسُولُ اللهِ ﷺ «صَلَاةُ اللَّيْلِ مَثْنَى مَثْنَى فَإِذَا خَشِيَ أَحَدُكُمُ الصُّبْحَ صَلَّى رَكْعَةً وَاحِدَةً تُوتِرُ لَهُ مَا قَدْ صَلَّى»  

"صَلاةُ اللَّيل مَثْنَى مَثْنَى، فَإِذَا خَشِى أَحَدُكُمُ الصُّبْحَ صَلَّى رَكْعَةً وَاحِدَةً تُوتِرُ لهُ مَا قَدْ صلَّى".  

"عَنِ ابْنِ عُمَرَ أَنَّ رَجُلًا قَالَ: يَا نَبِىَّ الله كيْفَ تَأمُرُنَا أَنْ نُصَلِّى منَ اللَّيْلِ؟ قَالَ: يُصَلِّى أحَدُكمْ مَثْنَى مَثْنَى، فَإِذَا خَشِىَ الصُّبْحَ صلَّى وَاحِدَةً أَوْتَرَ بِهَا مَا صلى مِنْ اللَّيْلِ".
