إِنَّ رَبَّكَ يَعلَمُ أَنَّكَ تَقومُ أَدنىٰ مِن ثُلُثَيِ اللَّيلِ وَنِصفَهُ وَثُلُثَهُ وَطائِفَةٌ مِنَ الَّذينَ مَعَكَ ۚ وَاللَّهُ يُقَدِّرُ اللَّيلَ وَالنَّهارَ ۚ عَلِمَ أَن لَن تُحصوهُ فَتابَ عَلَيكُم ۖ فَاقرَءوا ما تَيَسَّرَ مِنَ القُرآنِ ۚ عَلِمَ أَن سَيَكونُ مِنكُم مَرضىٰ ۙ وَآخَرونَ يَضرِبونَ فِي الأَرضِ يَبتَغونَ مِن فَضلِ اللَّهِ ۙ وَآخَرونَ يُقاتِلونَ في سَبيلِ اللَّهِ ۖ فَاقرَءوا ما تَيَسَّرَ مِنهُ ۚ وَأَقيمُوا الصَّلاةَ وَآتُوا الزَّكاةَ وَأَقرِضُوا اللَّهَ قَرضًا حَسَنًا ۚ وَما تُقَدِّموا لِأَنفُسِكُم مِن خَيرٍ تَجِدوهُ عِندَ اللَّهِ هُوَ خَيرًا وَأَعظَمَ أَجرًا ۚ وَاستَغفِرُوا اللَّهَ ۖ إِنَّ اللَّهَ غَفورٌ رَحيمٌ

Indeed, your Lord knows, [O Muhammad], 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 Allah determines [the extent of] the night and the day. He has known that you [Muslims] will not be able to do it and has turned to you in forgiveness, so recite what is easy [for you] of the Qur'an. 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 Allah and others fighting for the cause of Allah. So recite what is easy from it and establish prayer and give zakah and loan Allah a goodly loan. And whatever good you put forward for yourselves - you will find it with Allah. It is better and greater in reward. And seek forgiveness of Allah. Indeed, Allah is Forgiving and Merciful.
