Say, (O Prophet): “I call on my Lord alone, and I do not associate aught with Him in His Divinity.” 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, “No one will ever save me from Allah, and other than Him, I will not find any refuge.” 22 (My task is no more than) to deliver Allah's proclamation and His messages. And whoever disobeys Allah and His Messenger, surely the Fire of Hell awaits him; therein he will abide in perpetuity.” 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 whether that which you are promised is nigh, or whether my Lord will appoint for it a space; 25 He alone has knowledge of what is hidden. He reveals this to none, 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
