Surely We Ourselves have revealed the Quran to you revealing (it) in portions. 23 So wait patiently for the command of your Lord, and do not yield to anyone among them who is sinful or ungrateful; 24 Remember the name of thy Lord at morn and evening. 25 and during the night prostrate ourself before Him, and extol His glory for 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 We created them, and We strengthened their joints, but, when We will, We shall indeed exchange their likes. 28 Indeed, this is a reminder, so he who wills may take to his Lord a way. 29 But you will not unless God wills; surely God is ever All-knowing, All-wise. 30 He is Merciful to whom He will; but, for the harmdoers He has prepared for them a painful punishment. 31
