We have revealed the Qur'an to you gradually; 23 Therefore be patient with constancy to the Command of thy Lord, and hearken not to the sinner or the ingrate among them. 24 And mention the name of your Lord [in prayer] morning and evening 25 and in the night prostrate to Him; and exalt Him for a long night. 26 Surely these love the transitory and neglect a grievous day before 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 This is indeed a Reminder, so that he who will, takes a path to his Lord. 29 But ye will not, except as Allah wills; for Allah is full of Knowledge and Wisdom. 30 He is Merciful to whom He will; but, for the harmdoers He has prepared for them a painful punishment. 31
