Say: "I do no more than invoke my Lord, and I join not with Him any (false god)." 20 Say, "It is not in my power to cause you either harm or good?" 21 Say: 'From God shall protect me not anyone, and I shall find, apart from Him, no refuge, 22 "(Mine is) but conveyance (of the truth) from Allah and His Messages (of Islamic Monotheism), and whosoever disobeys Allah and His Messenger, then verily, for him is the Fire of Hell, he shall dwell therein forever." 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 know not whether the (Punishment) which ye are promised is near, or whether my Lord will appoint for it a distant term. 25 "He (alone) knows the Unseen, nor does He make any one acquainted with His Mysteries,- 26 Except to him whom He chooses as an apostle; for surely He makes a guard to march before him and after him, 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
