Truly, it is We who have revealed to you the Quran, a gradual revelation. 23 So persevere with the command of your Lord and do not pay any heed to the wicked and the unbelieving, 24 Remember the name of thy Lord at morn and evening. 25 And part of the night, prostrate thyself to Him; and glorify Him a long night through. 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 Surely this is a reminder, so whoever pleases takes to his Lord a way. 29 And you do not please except that Allah please, surely Allah is Knowing, Wise; 30 He is Merciful to whom He will; but, for the harmdoers He has prepared for them a painful punishment. 31
