The Wrapped Up

1,2,3,4,5) O the one who confines himself in his house![#15] Arise by the night -except for a short while; sometimes half of the night sometimes a little more or a little less- and serve! While conveying the Qur'an that is revealed to you, put in order properly! Indeed, we will cast upon you a very heavy word/the Qur'an.
6,7,8,9,10,11) Night time is more convenient/better in terms of studying in peace, more effective in terms of speaking/communication. Surely, there is a prolonged occupation for you by day.[#16] Remember the name of your Rabb and turn to Him completely! He is Rabb of the east and the west; of all directions. There is no deity except Him. Therefore, know Him as the One Who "arranges all creatures pursuant to a schedule and implements this schedule by supporting, maintaining it[#17]"! Be patient over what they say/they will say. And avoid them with good avoidance. Leave Me alone with those deniers who are owners of blessings! Give them respite a little.
12,13,14) Indeed, with Us are iron shackles to bind their feet and Jahannah [Hell]. And a food that chokes, a painful punishment. On that day; the earth and the mountains will convulse; the mountains will melt down and become a heap of sand flowing.
15,16,17,18,19) Indeed, We have sent you a messenger as a witness upon you, just as We sent a messenger to Pharaoh. But Pharaoh disobeyed the messenger so We seized him with a ruinous seizure. Then how will you guard yourselves from that day which will make children white-haired old men if you disbelieve; consciously deny the divinity of Allah and the fact that He is Rabb despite this? Even the heavens/universe will break apart with the severity of that day. And His promise which He has given to fulfill, will be fulfilled. Indeed, what is mentioned above; the Qur'an is a reminder/what makes you think. Therefore, whoever wills may take a path towards his Rabb.
20) Do not doubt, your Rabb knows that you stay awake for less than two-thirds, half, a third of the night. So does a group of those who are with you. Allah determines the night and the day by a measure. He has known that you will not be able to do this duty with ease so eased your duty. Then, learn and teach what is easy of the Qur'an! He has known that there will be those who are ill among you. He has known that some of them will travel through the earth seeking of the bounties of Allah, while some others will fight for the cause of Allah. Then learn teach what is easy from it! Establish/maintain Salah [financial and spiritual support; institutions that enlighten the community],[#18] give zaqah; the tax that the believers sincerely give as a liability of belief and duty of servitude so that the religion of Allah may be spread, maintained and Salah may be established[#19]! Loan Allah a good loan! And you will find whatever good you send forth for yourselves better and you will find its reward greater with Allah. Ask Allah for forgiveness! Indeed, Allah is the One Who forgives much, shows great mercy.[#20]
