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 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. 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.

Your Lord knows that you stand (in prayer) for nearly two thirds of the night, and (at times) for half of it, and (at times) for one third of it, and (so do) a group of those who are with you. And Allah measures the night and the day. He knows that you (O Muslims,) cannot do it in regular way; therefore He turned to you in mercy.Now, recite as much of the Qur’ān as is easy (for you). He knows that some of you may be sick, and others traveling in the land, seeking the grace of Allah, and yet others fighting in Allah’s way. Therefore, recite as much of it as is easy. And establish Salāh, and pay Zakāh, and advance to Allah a goodly loan. And whatever good you will send ahead for your own-selves, you will find it with Allah much better in condition, and much greater in reward. And seek forgiveness from Allah. Indeed Allah is Most-Forgiving, Very-Merciful.
