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: 'From God shall protect me not anyone, and I shall find, apart from Him, no refuge, 22 (It is) only a delivering (of communications) from Allah and His messages; and whoever disobeys Allah and His Apostle surely he shall have the fire of hell to abide therein for a long time. 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 (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 Knower He of the Unseen, and He discloses not His Unseen to anyone, 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 indeed conveyed the messages of their Lord. He surroundeth all their doings, and He keepeth count of all things. 28
