Truly, it is We who have revealed to you the Quran, a gradual revelation. 23 So submit patiently to thy Lord's command, and obey not of them any guilty one or disbeliever. 24 And celebrate the name of thy Lord morning and evening, 25 And part of the night, prostrate thyself to Him; and glorify Him a long night through. 26 Verily they love (the good of this world) that is hastily obtainable and are oblivious of the burdensome Day ahead of them. 27 We created them and fixed their bones and joints; and We could replace them when We like with others like them. 28 Verily this is an admonition; then whosoever will, may choose a way unto his Lord. 29 Yet you will not unless Allah wills; surely, Allah is the Knower, the Wise. 30 He admits into His mercy, whomever He wills; and for the unjust He has kept prepared a painful punishment. 31
