Truly, it is We who have revealed to you the Quran, a gradual revelation. 23 so be thou patient under the judgment of thy Lord, and obey not one of them, sinner or unbeliever. 24 Meditate upon the name of your Lord morning and evening; 25 And during the night - worship Him; and hallow Him the livelong night. 26 Verily those love the herein, and leave in front of them a heavy day. 27 We, even We, created them, and strengthened their frame. And when We will, We can replace them, bringing others like them in their stead. 28 Surely this is a reminder, so whoever pleases takes to his Lord a way. 29 And you do not will except that Allah wills. Indeed, Allah is ever Knowing and Wise. 30 He makes whom He pleases to enter into His mercy; and (as for) the unjust, He has prepared for them a painful chastisement. 31
