(O Prophet), indeed We have revealed the Qur'an to you in portions. 23 Therefore be patient with constancy to the Command of thy Lord, and hearken not to the sinner or the ingrate among them. 24 and remember the name of your Lord, morning and evening; 25 and during some of the night, and prostrate thyself before Him, and extol His limitless glory throughout the long night. 26 Lo! these love fleeting life, and put behind them (the remembrance of) a grievous 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 Surely this is a reminder, so whoever pleases takes to his Lord a way. 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
