Say: "I invoke my Sustainer alone, for I do not ascribe divinity to anyone beside Him." 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 (It is) only a delivering (of communications) from Allah and His messages; and whoever disobeys Allah and His Apostle surely he shall have the fire of hell to abide therein for a long time. 23 At length, when they see (with their own eyes) that which they are promised,- then will they know who it is that is weakest in (his) helper and least important in point of numbers. 24 Say (O Muhammad, unto the disbelievers): I know not whether that which ye are promised is nigh, or if my Lord hath set a distant term for it. 25 He is the Knower of the Unseen and does not disclose 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
