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: “None can protect me from Allah, nor can I find a refuge apart from Him. 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 When they see that which they were promised they shall know who is weaker in helpers and fewer in 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 Unknown, and He does not divulge His secret to any one 26 Other than an apostle He has chosen, when He makes a sentinel walk in front of him and a sentinel behind, 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
