Quran:
17:79
وَمِنَ ٱلَّيْلِ فَتَهَجَّدْ بِهِۦ نَافِلَةًۭ لَّكَ عَسَىٰٓ أَن يَبْعَثَكَ رَبُّكَ مَقَامًۭا مَّحْمُودًۭا ٧٩
And from [part of] the night, pray with it [i.e., recitation of the Qur’ān] as additional [worship] for you; it is expected that your Lord will resurrect you to a praised station.
25:64
وَٱلَّذِينَ يَبِيتُونَ لِرَبِّهِمْ سُجَّدًۭا وَقِيَـٰمًۭا ٦٤
And those who spend [part of] the night to their Lord prostrating and standing [in prayer]
32:16
تَتَجَافَىٰ جُنُوبُهُمْ عَنِ ٱلْمَضَاجِعِ يَدْعُونَ رَبَّهُمْ خَوْفًۭا وَطَمَعًۭا وَمِمَّا رَزَقْنَـٰهُمْ يُنفِقُونَ ١٦
Their sides part [i.e., they arise] from [their] beds; they supplicate their Lord in fear and aspiration, and from what We have provided them, they spend.
39:9
أَمَّنْ هُوَ قَـٰنِتٌ ءَانَآءَ ٱلَّيْلِ سَاجِدًۭا وَقَآئِمًۭا يَحْذَرُ ٱلْـَٔاخِرَةَ وَيَرْجُوا۟ رَحْمَةَ رَبِّهِۦ ۗ قُلْ هَلْ يَسْتَوِى ٱلَّذِينَ يَعْلَمُونَ وَٱلَّذِينَ لَا يَعْلَمُونَ ۗ إِنَّمَا يَتَذَكَّرُ أُو۟لُوا۟ ٱلْأَلْبَـٰبِ ٩
Is one who is devoutly obedient during periods of the night, prostrating and standing [in prayer], fearing the Hereafter and hoping for the mercy of his Lord, [like one who does not]? Say, “Are those who know equal to those who do not know?” Only they will remember [who are] people of understanding.
51:17
كَانُوا۟ قَلِيلًۭا مِّنَ ٱلَّيْلِ مَا يَهْجَعُونَ ١٧
They used to sleep but little of the night,[1]
[1]i.e., spending a portion of the night in prayer and supplication.
52:49
وَمِنَ ٱلَّيْلِ فَسَبِّحْهُ وَإِدْبَـٰرَ ٱلنُّجُومِ ٤٩
And in a part of the night exalt Him and after [the setting of] the stars.
73:2
قُمِ ٱلَّيْلَ إِلَّا قَلِيلًۭا ٢
Arise [to pray] the night, except for a little –
73:20
۞ إِنَّ رَبَّكَ يَعْلَمُ أَنَّكَ تَقُومُ أَدْنَىٰ مِن ثُلُثَىِ ٱلَّيْلِ وَنِصْفَهُۥ وَثُلُثَهُۥ وَطَآئِفَةٌۭ مِّنَ ٱلَّذِينَ مَعَكَ ۚ وَٱللَّهُ يُقَدِّرُ ٱلَّيْلَ وَٱلنَّهَارَ ۚ عَلِمَ أَن لَّن تُحْصُوهُ فَتَابَ عَلَيْكُمْ ۖ فَٱقْرَءُوا۟ مَا تَيَسَّرَ مِنَ ٱلْقُرْءَانِ ۚ عَلِمَ أَن سَيَكُونُ مِنكُم مَّرْضَىٰ ۙ وَءَاخَرُونَ يَضْرِبُونَ فِى ٱلْأَرْضِ يَبْتَغُونَ مِن فَضْلِ ٱللَّهِ ۙ وَءَاخَرُونَ يُقَـٰتِلُونَ فِى سَبِيلِ ٱللَّهِ ۖ فَٱقْرَءُوا۟ مَا تَيَسَّرَ مِنْهُ ۚ وَأَقِيمُوا۟ ٱلصَّلَوٰةَ وَءَاتُوا۟ ٱلزَّكَوٰةَ وَأَقْرِضُوا۟ ٱللَّهَ قَرْضًا حَسَنًۭا ۚ وَمَا تُقَدِّمُوا۟ لِأَنفُسِكُم مِّنْ خَيْرٍۢ تَجِدُوهُ عِندَ ٱللَّهِ هُوَ خَيْرًۭا وَأَعْظَمَ أَجْرًۭا ۚ وَٱسْتَغْفِرُوا۟ ٱللَّهَ ۖ إِنَّ ٱللَّهَ غَفُورٌۭ رَّحِيمٌۢ ٢٠
Indeed, your Lord knows, [O Muḥammad], that you stand [in prayer] almost two thirds of the night or half of it or a third of it, and [so do] a group of those with you. And Allāh determines [the extent of] the night and the day. He has known that you [Muslims] will not be able to do it[1] and has turned to you in forgiveness, so recite what is easy [for you] of the Qur’ān. He has known that there will be among you those who are ill and others traveling throughout the land seeking [something] of the bounty of Allāh and others fighting for the cause of Allāh. So recite what is easy from it and establish prayer and give zakāh and loan Allāh a goodly loan.[2] And whatever good you put forward for yourselves – you will find it with Allāh. It is better and greater in reward. And seek forgiveness of Allāh. Indeed, Allāh is Forgiving and Merciful.
[1]In the form of charities and contributions to His cause.
[2]Allāh has known that if they were to continue in such long periods of worship each night, the people would be caused much hardship.
Hadith:
حَدَّثَنَا أَبُو نُعَيْمٍ، قَالَ حَدَّثَنَا مِسْعَرٌ، عَنْ زِيَادٍ، قَالَ سَمِعْتُ الْمُغِيرَةَ ـ رضى الله عنه ـ يَقُولُ إِنْ كَانَ النَّبِيُّ صلى الله عليه وسلم لَيَقُومُ لِيُصَلِّيَ حَتَّى تَرِمُ قَدَمَاهُ أَوْ سَاقَاهُ، فَيُقَالُ لَهُ فَيَقُولُ “ أَفَلاَ أَكُونُ عَبْدًا شَكُورًا ”.
Narrated Al-Mughira: The Prophet (ﷺ) used to stand (in the prayer) or pray till both his feet or legs swelled. He was asked why (he offered such an unbearable prayer) and he said, “should I not be a thankful slave.”

حَدَّثَنَا أَبُو الْيَمَانِ، قَالَ أَخْبَرَنَا شُعَيْبٌ، عَنِ الزُّهْرِيِّ، قَالَ أَخْبَرَنِي سَالِمُ بْنُ عَبْدِ اللَّهِ، أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ ـ رضى الله عنهما ـ قَالَ إِنَّ رَجُلاً قَالَ يَا رَسُولَ اللَّهِ، كَيْفَ صَلاَةُ اللَّيْلِ قَالَ “ مَثْنَى مَثْنَى، فَإِذَا خِفْتَ الصُّبْحَ فَأَوْتِرْ بِوَاحِدَةٍ ”.
Narrated `Abdullah bin `Umar: A man said, “O Allah’s Messenger (ﷺ)! How is the prayer of the night?” He said, “Two rak`at followed by two rak`at and so on, and when you apprehend the approaching dawn, offer one rak`a as witr.”

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ، عَنْ مَالِكٍ، عَنِ ابْنِ شِهَابٍ، عَنْ أَبِي سَلَمَةَ، وَأَبِي عَبْدِ اللَّهِ الأَغَرِّ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ “ يَنْزِلُ رَبُّنَا تَبَارَكَ وَتَعَالَى كُلَّ لَيْلَةٍ إِلَى السَّمَاءِ الدُّنْيَا حِينَ يَبْقَى ثُلُثُ اللَّيْلِ الآخِرُ يَقُولُ مَنْ يَدْعُونِي فَأَسْتَجِيبَ لَهُ مَنْ يَسْأَلُنِي فَأُعْطِيَهُ مَنْ يَسْتَغْفِرُنِي فَأَغْفِرَ لَهُ ”.
Narrated Abu Huraira: Allah’s Messenger (ﷺ) (p.b.u.h) said, “Our Lord, the Blessed, the Superior, comes every night down on the nearest Heaven to us when the last third of the night remains, saying: “Is there anyone to invoke Me, so that I may respond to invocation? Is there anyone to ask Me, so that I may grant him his request? Is there anyone seeking My forgiveness, so that I may forgive him?”
