Say: 'I call only upon my Lord, and I do not associate with Him anyone. 20 Say, "I do not possess any power to harm or benefit you". 21 Say, "Indeed, there will never protect me from Allah anyone [if I should disobey], nor will I find in other than Him a refuge. 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 At length, when they see (with their own eyes) that which they are promised,- then will they know who it is that is weakest in (his) helper and least important in point of numbers. 24 Say: "I know not whether the (Punishment) which ye are promised is near, or whether my Lord will appoint for it a distant term. 25 (He is) the Knower of the Unseen, and He revealeth unto none His secret, 26 except the messenger whom He has chosen. He sends down guardians who walk before them and behind them, 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
