Say: "I call on my Lord alone and I do not associate any one with Him." 20 Say, "It is not in my power to cause you either harm or good?" 21 Say: 'From God shall protect me not anyone, and I shall find, apart from Him, no refuge, 22 Unless I convey from God and deliver His message." For those who disobey God and His Apostle is the fire of Hell, where they will abide for ever; 23 (On the Day of Judgment) when the disbelievers witness that with which they have been threatened, they will then know whose helpers are weaker and fewer in number. 24 Say: I do not know whether that with which you are threatened be nigh or whether my Lord will appoint for it a term: 25 He is the knower of the Unknown, and He does not divulge His secret to any one 26 Save unto an apostle chosen. And then He causeth to go before him and behind him a guard. 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
