Say: "I call on my Lord alone and I do not associate any one with Him." 20 Say thou: verily I own not for you power of hurt nor of benefit 21 Say thou: verily none can protect me from Allah, nor can I find beside Him any 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 Until when they see what they are threatened with, then shall they know who is weaker in helpers and fewer in number. 24 Say: 'I do not know whether that which you are promised is nigh, or whether my Lord will appoint for it a space; 25 (He is) the Knower of the Unseen, and He revealeth unto none His secret, 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
