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 prostrate for Him in a part of the night, and proclaim His purity into the long night. 26 Verily they love (the good of this world) that is hastily obtainable and are oblivious of the burdensome Day ahead of them. 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 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] -- God is indeed all-knowing and wise -- 30 He will admit to His Mercy whom He will; But the wrong-doers,- for them has He prepared a grievous Penalty. 31
