It is We Who have sent down the Qur'an to thee by stages. 23 So submit patiently to thy Lord's command, and obey not of them any guilty one or disbeliever. 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 Surely these men love the hasty world, and leave be behind them a heavy day. 27 It was We who created them and made their constitution strong, but if We wish we can replace them with others like them. 28 This surely is a reminder: Therefore whosoever desires may take the 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 For He admits into His mercy whomsoever He will; as for the evildoers, He has prepared for them a painful chastisement. 31
