Verily! It is We Who have sent down the Quran to you (O Muhammad SAW) by stages. 23 So submit patiently to thy Lord's command, and obey not of them any guilty one or disbeliever. 24 Remember the name of thy Lord at morn and evening. 25 And prostrate for Him in a part of the night, and proclaim His purity into the long night. 26 Verily! These (disbelievers) love the present life of this world, and put behind them a heavy Day (that will be hard). 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 This is indeed a Reminder, so that he who will, takes a path to his Lord. 29 But you cannot will it unless God wills [to show you that way] -- God is indeed all-knowing and wise -- 30 For He admits into His mercy whomsoever He will; as for the evildoers, He has prepared for them a painful chastisement. 31
