Verily! It is We Who have sent down the Quran to you (O Muhammad SAW) by stages. 23 Wherefore persevere thou with the commandment of thy Lord, and obey not thou of them, any sinner or ingrate. 24 And remember thou the name of thy Lord in the morning and in the evening. 25 And prostrate for Him in a part of the night, and proclaim His purity into the long night. 26 Surely these men love the hasty world, and leave be behind them a heavy day. 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 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 admits to His Mercy whomsoever He pleases. As for the wrong-doers, He has prepared for them a grievous chastisement. 31
