Say, "I call only upon my Lord and do not associate anyone else with Him." 20 Say: "It is not in my power to cause you harm, or to bring you to right conduct." 21 Say: Surely no one can protect me against Allah, nor can I find besides Him any place of refuge: 22 (It is) only a delivering (of communications) from Allah and His messages; and whoever disobeys Allah and His Apostle surely he shall have the fire of hell to abide therein for a long time. 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 whether that which you are promised is nigh, or whether my Lord will appoint for it a space; 25 He is the knower of the Unknown, and He does not divulge His secret to any one 26 Except whom He has approved of messengers, and indeed, He sends before each messenger and behind him observers 27 In order to see that they have conveyed the messages of their Lord – and His knowledge encompasses all whatever they have, and He has kept all things accounted for. 28
