Say: 'I call only upon my Lord, and I do not associate with Him anyone. 20 Say, "It is not in my power to cause you either harm or good?" 21 Say: Surely no one can protect me against Allah, nor can I find besides Him any place of refuge: 22 Unless I convey from God and deliver His message." For those who disobey God and His Apostle is the fire of Hell, where they will abide 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 (Muhammad), say, "I do not know whether that with which you have been threatened is close by or whether my Lord will prolong the time of its coming. 25 He is the Knower of the unseen, and He discloseth not His unseen unto anyone. 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 So that He may know if they have delivered their Lord's messages. He comprehends all that has been given them, and keeps count of everything. 28
