Say, [O Muhammad], "I only invoke my Lord and do not associate with Him anyone." 20 Say, "It is not in my power to cause you either harm or good?" 21 Say: "Verily, no one could ever protect me from God, nor could I ever find a place to hide from Him 22 My duty is only to convey that which I receive from Him and His messages." For those who disobey God and His Messenger there is the fire of hell, wherein they will abide forever. 23 At length, when they see (with their own eyes) that which they are promised,- then will they know who it is that is weakest in (his) helper and least important in point of 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 discloseth not His unseen unto anyone. 26 except only to a Messenger that He has chosen, and He sends guardians 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
