Say, (O Prophet): “I call on my Lord alone, and I do not associate aught with Him in His Divinity.” 20 Say: “Surely neither it is in my power to hurt you nor to bring you to the Right Way.” 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 Till (the day) when they shall behold that which they are promised (they may doubt); but then they will know (for certain) who is weaker in allies and less in multitude. 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 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
