Say, [O Muhammad], "I only invoke my Lord and do not associate with Him anyone." 20 Say, "I do not possess any power to harm or benefit you". 21 Say (O Muhammad SAW): "None can protect me from Allah's punishment (if I were to disobey Him), nor should I find refuge except in Him. 22 Mine is but the publishing from Allah and His messages; and whosoever disobeyeth Allah and His apostle, his portion verily is the Hell-Fire as abiders therein for evermore. 23 Till (the day) when they shall behold that which they are promised (they may doubt); but then they will know (for certain) who is weaker in allies and less in multitude. 24 Say: "I do not know if what is promised you is near, or if my Lord prolongs its term. 25 He alone has knowledge of what is hidden. He reveals this to none, 26 Save unto an apostle chosen. And then He causeth to go before him and behind him a guard. 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
