Say, [O Muhammad], "I only invoke my Lord and do not associate with Him anyone." 20 Say: "Verily, it is not in my power to cause you harm or to endow you with consciousness of what is right." 21 Say: 'None shall protect me from Allah, and other than Him, I will find 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 [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 Say, "I do not know if what you are promised is near or if my Lord will grant for it a [long] period." 25 He alone has knowledge of what is hidden. He reveals this to none, 26 other than to a Messenger whom He chooses (for the bestowal of any part of the knowledge of the Unseen), whereafter He appoints guards who go before him and behind him, 27 (Messenger) so that He would know that the Messengers have conveyed the message of their Lord. He encompasses all that is with them and He keeps a precise account of all things". 28
