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 deliver me from Allah (If I were to disobey Him), nor should I find refuge except in 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 [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) the All-Knower of the Gha'ib (unseen), and He reveals to none His Gha'ib (unseen)." 26 Except whom He has approved of messengers, and indeed, He sends before each messenger and behind him observers 27 (Messenger) so that He would know that the Messengers have conveyed the message of their Lord. He encompasses all that is with them and He keeps a precise account of all things". 28
