سورة المزمل          

      O you who wraps himself [in clothing], (1) Arise [to pray] the night, except for a little - (2) Half of it - or subtract from it a little (3) Or add to it, and recite the Qur'an with measured recitation. (4) Indeed, We will cast upon you a heavy word. (5) Indeed, the hours of the night are more effective for concurrence [of heart and tongue] and more suitable for words. (6) Indeed, for you by day is prolonged occupation. (7) And remember the name of your Lord and devote yourself to Him with [complete] devotion. (8) [He is] the Lord of the East and the West; there is no deity except Him, so take Him as Disposer of [your] affairs. (9) And be patient over what they say and avoid them with gracious avoidance. (10) And leave Me with [the matter of] the deniers, those of ease [in life], and allow them respite a little. (11) Indeed, with Us [for them] are shackles and burning fire (12) 

        And food that chokes and a painful punishment - (13) On the Day the earth and the mountains will convulse and the mountains will become a heap of sand pouring down. (14) Indeed, We have sent to you a Messenger as a witness upon you just as We sent to Pharaoh a messenger. (15) But Pharaoh disobeyed the messenger, so We seized him with a ruinous seizure. (16) Then how can you fear, if you disbelieve, a Day that will make the children white- haired? (17) The heaven will break apart therefrom; ever is His promise fulfilled. (18) Indeed, this is a reminder, so whoever wills may take to his Lord a way. (19)

      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. (20)
