Say, "I call only upon my Lord and do not associate anyone else with Him." 20 Say, "I do not possess any power to harm or benefit you". 21 Say: “None can protect me from Allah, nor can I find a refuge apart from 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 Until, when they see that which they are promised, then they will know who is weaker in helpers and fewer in numbers. 24 Say: "I do not know if what is promised you is near, or if my Lord prolongs its term. 25 He is the Knower of the Unseen, and He does not disclose His Unseen to anyone 26 Other than an apostle He has chosen, when He makes a sentinel walk in front of him and a sentinel behind, 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
