Verily, your Lord knows that you do stand (to pray at night) a little less than two-thirds of the night, or half the night, or a third of the night, and so do a party of those with you, And Allah measures the night and the day. He knows that you are unable to pray the whole night, so He has turned to you (in mercy). So, recite you of the Quran as much as may be easy for you. He knows that there will be some among you sick, others travelling through the land, seeking of Allah's Bounty; yet others fighting in Allah's Cause. So recite as much of the Quran as may be easy (for you), and perform As-Salat (Iqamat-as-Salat) and give Zakat, and lend to Allah a goodly loan, and whatever good you send before you for yourselves, (i.e. Nawafil non-obligatory acts of worship: prayers, charity, fasting, Hajj and 'Umrah, etc.), you will certainly find it with Allah, better and greater in reward. And seek Forgiveness of Allah. Verily, Allah is Oft-Forgiving, Most-Merciful.
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.
