Verily We! it is We Who have revealed unto thee the Qur'an, a gradual revelation. 23 So be patient for the decision of your Lord and do not obey from among them a sinner or ungrateful [disbeliever]. 24 And remember the Name of thy Lord at dawn and in the evening 25 and part of the night; bow down before Him and magnify Him through 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 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 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]: for, behold, God is indeed all-seeing, 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
