We have revealed the Qur'an to you gradually; 23 so be thou patient under the judgment of thy Lord, and obey not one of them, sinner or unbeliever. 24 And remember thou the name of thy Lord in the morning and in the evening. 25 And worship Him (a portion) of the night. And glorify Him through the livelong night. 26 Verily! These (disbelievers) love the present life of this world, and put behind them a heavy Day (that will be hard). 27 We created them and strengthened their joints; and whenever We wish, We can change their faces entirely. 28 Verily this is an Exhortation; so let him who so will take a way to his Lord. 29 And ye will not, unless Allah willeth. Verily Allah is ever Knowing, Wise. 30 He is Merciful to whom He will; but, for the harmdoers He has prepared for them a painful punishment. 31
