Lo! We, even We, have revealed unto thee the Qur'an, a revelation; 23 So persevere with the command of your Lord and do not pay any heed to the wicked and the unbelieving, 24 and remember the name of your Lord, morning and evening; 25 And during part of the night adore Him, and give glory to Him (a) long (part of the) night. 26 Those people [who are unmindful of God] aspire for immediate gains, and put 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 Verily this is an Exhortation; so let him who so will take a way 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
