(O Prophet), indeed We have revealed the Qur'an to you in portions. 23 so be thou patient under the judgment of thy Lord, and obey not one of them, sinner or unbeliever. 24 And mention the name of your Lord [in prayer] morning and evening 25 and in the night prostrate to Him; and exalt Him for a long night. 26 Verily! These (disbelievers) love the present life of this world, and put behind them a heavy Day (that will be hard). 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 Verily this is an admonition; then whosoever will, may choose a way unto his Lord. 29 And ye will not, unless Allah willeth. Verily Allah is ever Knowing, Wise. 30 He admits to His mercy whomever He wants. For the unjust He has prepared a painful punishment. 31
