Say: I only call upon my Lord, and I do not associate any one with Him. 20 Say: "It is not in my power to cause you harm, or to bring you to the Right Path." 21 Say, "Indeed, there will never protect me from Allah anyone [if I should disobey], nor will I find in other than Him a 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 They shall go on denying until they; behold that which they are promised wherefore then they shall know who were weaker in protectors and fewer in number. 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 [alone] knows that which is beyond the reach of a created being's perception, and to none does He disclose aught of the mysteries of His Own unfathomable knowledge, 26 Except whom He has approved of messengers, and indeed, He sends before each messenger and behind him observers 27 that He may know they have delivered the Messages of their Lord; and He encompasses all that is with them, and He has numbered everything in numbers.' 28
