Truly, it is We who have revealed to you the Quran, a gradual revelation. 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 remember the name of your Lord morning and evening. 25 and prostrate yourself before Him at night, and extol His Glory during the long watches of the night. 26 Surely these love the transitory and neglect a grievous day before them. 27 We created them, and We strengthened their joints; and, when We will, We shall exchange their likes. 28 Lo! this is an Admonishment, that whosoever will may choose a way unto his Lord. 29 But you cannot will, unless Allah wills. Verily, Allah is Ever All-Knowing, All-Wise. 30 He will admit to His Mercy whom He will; But the wrong-doers,- for them has He prepared a grievous Penalty. 31
