We have revealed the Qur'an to you gradually; 23 So wait patiently for the command of your Lord, and do not yield to anyone among them who is sinful or ungrateful; 24 And mention the name of your Lord [in prayer] morning and evening 25 And part of the night, prostrate thyself to Him; and glorify Him a long night through. 26 Indeed, these [disbelievers] love the immediate and leave behind them a grave Day. 27 [They will not admit to themselves that] it We who have created them and strengthened their make - and [that] if it be Our will We can replace them entirely with others of their kind. 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 will admit to His Mercy whom He will; But the wrong-doers,- for them has He prepared a grievous Penalty. 31
