(Muhammad), say, "I worship only my Lord and do not consider anyone equal to Him". 20 Say: 'Surely I possess no power over you, either for hurt or for rectitude.' 21 Say: 'None shall protect me from Allah, and other than Him, I will find no refuge, 22 My only (means of protection) is to convey the message of God. Whoever disobeys God and His Messenger will go to hell, wherein he will live 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 do not know whether what you are promised is imminent, or whether my Lord has set for it a far-off day. 25 He is the knower of the Unknown, and He does not divulge His secret to any one 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 as to make manifest that it is indeed [but] their Sustainer's messages that these [apostles] deliver: for it is He who encompasses [with His knowledge] all that they have [to say,] just as He takes count, one by one, of everything [that exists]. 28
