We have revealed the Qur'an to you gradually; 23 So persevere with the command of your Lord and do not pay any heed to the wicked and the unbelieving, 24 Remember the name of thy Lord at morn and evening. 25 and part of the night; bow down before Him and magnify Him through the long night. 26 Indeed, these love the hasty life, and are heedless and leave behind them a heavy Day. 27 It is We Who created them, and strengthened their skeleton; and We can replace them with others like them, whenever We will. 28 Verily this is an Exhortation; so let him who so will take a way to his Lord. 29 Yet you will not unless Allah wills; surely, Allah is the Knower, the Wise. 30 For He admits into His mercy whomsoever He will; as for the evildoers, He has prepared for them a painful chastisement. 31
