Say, "I call only upon my Lord and do not associate anyone else with Him." 20 Say: "It is not in my power to cause you harm, or to bring you to right conduct." 21 Say: Surely no one can protect me against Allah, nor can I find besides Him any place of refuge: 22 But [I have for you] only notification from Allah, and His messages." And whoever disobeys Allah and His Messenger - then indeed, for him is the fire of Hell; they will abide therein forever. 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 (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 has knowledge of what is hidden. He reveals this to none, 26 Other than an apostle He has chosen, when He makes a sentinel walk in front of him and a sentinel behind, 27 So that He may know if they have delivered their Lord's messages. He comprehends all that has been given them, and keeps count of everything. 28
