أَقِمِ ٱلصَّلَوٰةَ لِدُلُوكِ ٱلشَّمْسِ إِلَىٰ غَسَقِ ٱلَّيْلِ وَقُرْءَانَ ٱلْفَجْرِ ۖ إِنَّ قُرْءَانَ ٱلْفَجْرِ كَانَ مَشْهُودًا

Establish prayer at the decline of the sun [from its meridian] until the darkness of the night1 and [also] the Qur’ān [i.e., recitation] of dawn.2 Indeed, the recitation of dawn is ever witnessed.

Al-Isra 78

وَمِنَ ٱلَّيْلِ فَتَهَجَّدْ بِهِۦ نَافِلَةً لَّكَ عَسَىٰٓ أَن يَبْعَثَكَ رَبُّكَ مَقَامًا مَّحْمُودًا

And from [part of] the night, pray1 with it [i.e., recitation of the Qur’ān] as additional [worship] for you; it is expected that2 your Lord will resurrect you to a praised station.3

Al-Isra 79

ٱتْلُ مَآ أُوحِىَ إِلَيْكَ مِنَ ٱلْكِتَـٰبِ وَأَقِمِ ٱلصَّلَوٰةَ ۖ إِنَّ ٱلصَّلَوٰةَ تَنْهَىٰ عَنِ ٱلْفَحْشَآءِ وَٱلْمُنكَرِ ۗ وَلَذِكْرُ ٱللَّهِ أَكْبَرُ ۗ وَٱللَّهُ يَعْلَمُ مَا تَصْنَعُونَ

Recite, [O Muḥammad], what has been revealed to you of the Book and establish prayer. Indeed, prayer prohibits immorality and wrongdoing, and the remembrance of Allāh is greater. And Allāh knows that which you do.

Al-Ankabut 45

إِنَّ ٱلَّذِينَ يَتْلُونَ كِتَـٰبَ ٱللَّهِ وَأَقَامُوا۟ ٱلصَّلَوٰةَ وَأَنفَقُوا۟ مِمَّا رَزَقْنَـٰهُمْ سِرًّا وَعَلَانِيَةً يَرْجُونَ تِجَـٰرَةً لَّن تَبُورَ

Indeed, those who recite the Book of Allāh and establish prayer and spend [in His cause] out of what We have provided them, secretly and publicly, [can] expect a transaction [i.e., profit] that will never perish -

Fatir 29

۞ إِنَّ رَبَّكَ يَعْلَمُ أَنَّكَ تَقُومُ أَدْنَىٰ مِن ثُلُثَىِ ٱلَّيْلِ وَنِصْفَهُۥ وَثُلُثَهُۥ وَطَآئِفَةٌ 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 حَسَنًا ۚ وَمَا تُقَدِّمُوا۟ لِأَنفُسِكُم مِّنْ خَيْرٍ تَجِدُوهُ عِندَ ٱللَّهِ هُوَ خَيْرًا وَأَعْظَمَ أَجْرًا ۚ وَٱسْتَغْفِرُوا۟ ٱللَّهَ ۖ إِنَّ ٱللَّهَ غَفُورٌ رَّحِيمٌۢ

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 it1 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.
