Say, (O Prophet): “I call on my Lord alone, and I do not associate aught with Him in His Divinity.” 20 Say: I do not control for you evil or good. 21 Say, "No one can protect me from God, nor can I find any place of refuge but with him. 22 My duty is only to convey that which I receive from Him and His messages." For those who disobey God and His Messenger there is the fire of hell, wherein they will abide forever. 23 [Let them, then, wait] until the time when they behold that [doom] of which they were forewarned: for then they will come to understand which [kind of man] is more helpless and counts for less! 24 Say, "I do not know if what you are promised is near or if my Lord will grant for it a [long] period." 25 "He (alone) knows the Unseen, nor does He make any one acquainted with His Mysteries,- 26 Save unto every messenger whom He hath chosen, and then He maketh a guard to go before him and a guard behind him 27 (Messenger) so that He would know that the Messengers have conveyed the message of their Lord. He encompasses all that is with them and He keeps a precise account of all things". 28
