It is We Who have sent down the Qur'an to thee by stages. 23 So persevere with the command of your Lord and do not pay any heed to the wicked and the unbelieving, 24 Mention the Name of your Lord, mornings and evenings. 25 And worship Him (a portion) of the night. And glorify Him through the livelong 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 We, even We, created them, and strengthened their frame. And when We will, We can replace them, bringing others like them in their stead. 28 Verily this is an Exhortation; so let him who so will take a way to his Lord. 29 But you will not unless God wills; surely God is ever All-knowing, All-wise. 30 He admits whoever He will into His grace and has prepared a painful punishment for the evil doers. 31
