Say: "I do no more than invoke my Lord, and I join not with Him any (false god)." 20 Say: "Verily, it is not in my power to cause you harm or to endow you with consciousness of what is right." 21 Say, "Indeed, there will never protect me from Allah anyone [if I should disobey], nor will I find in other than Him a refuge. 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 [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 near, or whether my Lord will set for it a time. 25 He is the knower of the Unknown, and He does not divulge His secret to any one 26 Except to him whom He chooses as an apostle; for surely He makes a guard to march before him and after 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
