Indeed, it is We who have sent down to you, [O Muhammad], the Qur'an progressively. 23 So be patient for the decision of your Lord and do not obey from among them a sinner or ungrateful [disbeliever]. 24 and bear in mind thy Sustainer's name at morn and evening 25 And during the night prostrate to Him and exalt Him a long [part of the] night. 26 As to these, they love the fleeting life, and put away behind them a Day (that will be) hard. 27 [They will not admit to themselves that] it We who have created them and strengthened their make - and [that] if it be Our will We can replace them entirely with others of their kind. 28 This is indeed an advice; so whoever wishes may take the path towards his Lord. 29 But your willing shall be of no avail until Allah Himself so wills. Surely Allah is All-Knowing, Most Wise. 30 He admits into His mercy, whomever He wills; and for the unjust He has kept prepared a painful punishment. 31
