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

Your Lord knows that you stand for nearly two-thirds of the night, or half of it, or a third of it, and so do a party of those who are with you. God regulates the night and the day. He knew that you wouldn’t be able to do it, so He relented towards you. Read what’s easy from the Quran. He knows that some of you may be ill, others traveling through the land seeking God’s bounty, and others fighting in God’s cause. So read what’s easy from it. Establish prayer, give the purifying charity, and lend God a good loan. Whatever good you forward for yourselves, you’ll find it with God, better and more significant in reward. And seek forgiveness from God; God is Forgiving and Merciful.
