Verse 20

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

Your Lord knows that you indeed stay up nearly two-thirds of the night or half of it, or a third of it, and so do a group of those with you. However, God has designed the night and the day. He knows that you cannot do this all the time; He thus has accepted your repentance, therefore, read from the Quran whatever you can. He knows that some of you are ill, and others are traveling seeking God’s bounty and yet others are striving in the cause of God, so read from it as much as possible. And observe the contact prayer and give the cleansing charity and give God a loan of righteousness. And whatever good you send forth on behalf of your souls you will find it as a better reward with God. And ask God for forgiveness for indeed God is All Forgiving, All Merciful.
