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: Lo! none can protect me from Allah, nor can I find any refuge beside Him 22 My duty is only to convey that which I receive from Him and His messages." For those who disobey God and His Messenger there is the fire of hell, wherein they will abide forever. 23 [The disbelievers continue] until, when they see that which they are promised, then they will know who is weaker in helpers and less in number. 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 Except whom He has approved of messengers, and indeed, He sends before each messenger and behind him observers 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
