Indeed, it is We who have sent down to you, [O Muhammad], the Qur'an progressively. 23 So persevere with the command of your Lord and do not pay any heed to the wicked and the unbelieving, 24 And remember the Name of your Lord every morning and afternoon [i.e. offering of the Morning (Fajr), Zuhr, and 'Asr prayers]. 25 and part of the night; bow down before Him and magnify Him through the long night. 26 Surely these men love the hasty world, and leave be behind them a heavy day. 27 It is We Who created them, and We have made them of strong built. And when We will, We can replace them with others like them with a complete replacement. 28 Surely this is a Reminder; so he who will, takes unto his Lord a way. 29 But you cannot will it unless God wills [to show you that way] -- God is indeed all-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
