Say, [O Muhammad], "I only invoke my Lord and do not associate with Him anyone." 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: 'None shall protect me from Allah, and other than Him, I will find no refuge, 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 They shall go on denying until they; behold that which they are promised wherefore then they shall know who were weaker in protectors and fewer in number. 24 Say: I do not know whether that with which you are threatened be nigh or whether my Lord will appoint for it a term: 25 He is the Knower of the unseen, and He discloseth not His unseen unto anyone. 26 unless it be to an apostle whom He has been pleased to elect [there for]: and then He sends forth [the forces of heaven] to watch over him in whatever lies open before him and in what is beyond his ken 27 So that He may know if they have delivered their Lord's messages. He comprehends all that has been given them, and keeps count of everything. 28
