Say, [O Muhammad], "I only invoke my Lord and do not associate with Him anyone." 20 Say, "I do not possess any power to harm or benefit you". 21 Say: "No one can save me from God, nor can I find a place of refuge apart from 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 know not whether what you are promised is near or whether my Lord will prolong its term. 25 Knower He of the Unseen, and He discloses not His Unseen to anyone, 26 except the messenger whom He has chosen. He sends down guardians who walk before them and behind them, 27 that He may know they have delivered the Messages of their Lord; and He encompasses all that is with them, and He has numbered everything in numbers.' 28
