Say: I only call upon my Lord, and I do not associate any one with Him. 20 Say, "It is not in my power to cause you either harm or good?" 21 Say, “No one will ever save me from Allah, and other than Him, I will not find any 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 [Let them, then, wait] until the time when they behold that [doom] of which they were forewarned: for then they will come to understand which [kind of man] is more helpless and counts for less! 24 Say, "I do not know if what you are promised is near or if my Lord will grant for it a [long] period." 25 "He (alone) knows the Unseen, nor does He make any one acquainted with His Mysteries,- 26 except the messenger whom He has chosen. He sends down guardians who walk before them and behind them, 27 That He may know that they have preached the message of their Lord. And He comprehendeth whatever is with them, and He keepeth count of everything numbered. 28
