Verily We! it is We Who have revealed unto thee the Qur'an, a gradual revelation. 23 So wait patiently for the command of your Lord, and do not yield to anyone among them who is sinful or ungrateful; 24 And celebrate the name of thy Lord morning and evening, 25 And during part of the night adore Him, and give glory to Him (a) long (part of the) night. 26 Surely these love the transitory and neglect a grievous day before them. 27 We created them, and We strengthened their joints, but, when We will, We shall indeed exchange their likes. 28 Lo! this is an Admonishment, that whosoever will may choose a way unto 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 will admit to His Mercy whom He will; But the wrong-doers,- for them has He prepared a grievous Penalty. 31
