Verily We! it is We Who have revealed unto thee the Qur'an, a gradual revelation. 23 so be thou patient under the judgment of thy Lord, and obey not one of them, sinner or unbeliever. 24 And remember the Name of thy Lord at dawn and in the evening 25 and during the night prostrate ourself before Him, and extol His glory for a long part of the night. 26 Surely these love the transitory and neglect a grievous day before them. 27 It is We Who creared them and made them firm of make. And whenever We list, We can replace them with others like unto them. 28 This surely is a reminder: Therefore whosoever desires may take the way to his Lord. 29 Yet you will not unless Allah wills; surely, Allah is the Knower, the Wise. 30 He will admit to His Mercy whom He will; But the wrong-doers,- for them has He prepared a grievous Penalty. 31
