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 And mention the name of your Lord [in prayer] morning and evening 25 And during the night - worship Him; and hallow Him the livelong night. 26 Indeed, these love the hasty life, and are heedless and leave behind them a heavy Day. 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 This is an admonition: Whosoever will, let him take a (straight) Path to his Lord. 29 But your willing shall be of no avail until Allah Himself so wills. Surely Allah is All-Knowing, Most Wise. 30 He admits to His mercy whomever He wants. For the unjust He has prepared a painful punishment. 31
