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: '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 [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 thou: I know not whether that which ye are promised is nigh, or whether my Lord hath appointed for it a distant term. 25 He is the Knower of the Unseen, and He does not disclose His Unseen to anyone 26 except only to a Messenger that He has chosen, and He sends guardians before him and behind him, 27 so that He may know that they have delivered the messages of their Lord. He encompasses in His knowledge their surroundings and keeps a count of all things.” 28
