Say, [O Muhammad], "I only invoke my Lord and do not associate with Him anyone." 20 Say: 'Indeed, I possess no power over you, either for harm or for guidance' 21 Say: 'From God shall protect me not anyone, and I shall find, apart from Him, no refuge, 22 except a deliverance from Allah and His Messages. He who disobeys Allah and His Messenger, for him is the Fire of Gehenna, which he will be in for ever. 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 do not know whether that with which you are threatened be nigh or whether my Lord will appoint for it a term: 25 (He is) the Knower of the Unseen, and He revealeth unto none His secret, 26 Save unto an apostle chosen. And then He causeth to go before him and behind him a guard. 27 "That He may know that they have (truly) brought and delivered the Messages of their Lord: and He surrounds (all the mysteries) that are with them, and takes account of every single thing." 28
