Verily We! it is We Who have revealed unto thee the Qur'an, 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 And glorify the name of your Lord morning and evening. 25 And during the night - worship Him; and hallow Him the livelong night. 26 As to these, they love the fleeting life, and put away behind them a Day (that will be) hard. 27 It is We Who created them, and We have made their joints strong; but, when We will, We can substitute the like of them by a complete change. 28 This is a reminder. Let whoever wishes, take the right path to his Lord. 29 And what will you wish, except if Allah wills; indeed Allah is All Knowing, Wise. 30 He maketh whom He will to enter His mercy, and for evil-doers hath prepared a painful doom. 31
