Verily, the rising by night (for Tahajjud prayer) is very hard and most potent and good for governing oneself, and most suitable for (understanding) the Word (of Allah).
(He Alone is) the Lord of the east and the west; La ilaha illa Huwa (none has the right to be worshipped but He). So take Him Alone as Wakil (Disposer of your affairs).
And leave Me Alone to deal with the beliers (those who deny My Verses), those who are in possession of good things of life. And give them respite for a little while.
Verily, We have sent to you (O men) a Messenger (Muhammad صلى الله عليه وسلم) to be a witness over you, as We did send a Messenger [Musa (Moses)] to Fir'aun (Pharaoh).
Thy Lord doth know that thou standest forth (to prayer) nigh two - thirds of the night, or half the night, or a third of the night, and so doth a party of those with thee. But Allah doth appoint night and day in due measure He knoweth that ye are unable to keep count thereof. So He hath turned to you (in mercy): read ye, therefore, of the Qur'an as much as may be easy for you. He knoweth that there may be (some) among you in ill - health; others travelling through the land, seeking of Allah's bounty; yet others fighting in Allah's Cause, read ye, therefore, as much of the Qur'an as may be easy (for you); and establish regular Prayer and give regular Charity; and loan to Allah a Beautiful Loan. And whatever good ye send forth for your souls ye shall find it in Allah's Presence, - yea, better and greater, in Reward and seek ye the Grace of Allah: for Allah is Oft - Forgiving, Most Merciful.
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 also 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 Qur'an 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 Qur'an 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), you will certainly find it with Allah, better and greater in reward. And seek Forgiveness of Allah. Verily, Allah is Oft-Forgiving, Most-Merciful .
