Say thou: I simply call upon Allah, and I associate not with Him any-one. 20 Say, "It is not in my power to cause you either harm or good?" 21 Say, "No one can protect me from God, nor can I find any place of refuge but with him. 22 "Unless I proclaim what I receive from Allah and His Messages: for any that disobey Allah and His Messenger,- for them is Hell: they shall dwell therein for ever." 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: 'I do not know whether that which you are promised is near, or whether my Lord will set for it a time. 25 Knower He of the Unseen, and He discloses not His Unseen to anyone, 26 Except to a Messenger (from mankind) whom He has chosen (He informs him of unseen as much as He likes), and then He makes a band of watching guards (angels) to march before him and behind him. 27 That he may know that they have conveyed the messages of their Lord; and He has encompassed whatever is with them and has enumerated all things in number. 28
