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 harm, or to bring you to right conduct." 21 Say, "Surely no one can protect me against God, nor can I find besides Him any place of refuge. 22 Unless I convey from God and deliver His message." For those who disobey God and His Apostle is the fire of Hell, where they will abide for ever; 23 (They shall not change their ways) until they see that against which they had been warned, and then they will know whose helpers are weaker and whose supporters are fewer in number. 24 Say, "I do not know whether what you are promised is imminent, or whether my Lord has set for it a far-off day. 25 "He (alone) knows the Unseen, nor does He make any one acquainted with His Mysteries,- 26 Except to a Messenger (from mankind) whom He has chosen (He informs him of unseen as much as He likes), and then He makes a band of watching guards (angels) to march before him and behind him. 27 So that He may know that they have truly delivered the messages of their Lord, and He encompasses what is with them and He records the number of all things. 28
