Say, [O Muhammad], "I only invoke my Lord and do not associate with Him anyone." 20 Say: 'Surely I possess no power over you, either for hurt or for rectitude.' 21 Say: 'From God shall protect me not anyone, and I shall find, apart from Him, no refuge, 22 (Mine is) but conveyance (of the Truth) from Allah, and His messages; and whoso disobeyeth Allah and His messenger, lo! his is fire of hell, wherein such dwell for ever. 23 Till, when they see that which they are promised, then they will know who it is that is weaker concerning helpers and less important concerning 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 (alone) knows the Unseen, nor does He make any one acquainted with His Mysteries,- 26 other than to a Messenger whom He chooses (for the bestowal of any part of the knowledge of the Unseen), whereafter He appoints guards who go before him and behind him, 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
