It is We Who have sent down the Qur'an to thee by stages. 23 Therefore wait patiently for the command of your Lord, and obey not from among them a sinner or an ungrateful one. 24 And glorify the name of your Lord morning and evening. 25 And during the night prostrate to Him and exalt Him a long [part of the] 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 creared them and made them firm of make. And whenever We list, We can replace them with others like unto them. 28 Verily this is an Exhortation; so let him who so will take a way 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 admits into His mercy, whomever He wills; and for the unjust He has kept prepared a painful punishment. 31
