VERILY, [O believer,] it is We who have bestowed from on high this Qur'an upon thee, step by step - truly a bestowal from on high! 23 So persevere with the command of your Lord and do not pay any heed to the wicked and the unbelieving, 24 and bear in mind thy Sustainer's name at morn and evening 25 And during the night - worship Him; and hallow Him the livelong night. 26 Indeed, these [disbelievers] love the immediate and leave behind them a grave Day. 27 It was We who created them and made their constitution strong, but if We wish we can replace them with others like them. 28 Surely this is a Reminder; so he who will, takes unto his Lord a way. 29 And what will you wish, except if Allah wills; indeed Allah is All Knowing, 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
