Verily We! it is We Who have revealed unto thee the Qur'an, a gradual revelation. 23 So wait patiently for the command of your Lord and do not yield to any sinful or disbelieving person among them (people). 24 and remember the name of your Lord, morning and evening; 25 And prostrate for Him in a part of the night, and proclaim His purity into the long night. 26 Surely men love what hastes away and forget the grievous day (ahead). 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 Lo! this is an Admonishment, that whosoever will may choose a way unto his Lord. 29 But ye will not, except as Allah wills; for Allah is full of Knowledge and Wisdom. 30 He is Merciful to whom He will; but, for the harmdoers He has prepared for them a painful punishment. 31
