Say (unto them, O Muhammad): I pray unto Allah only, and ascribe unto Him no partner. 20 Say, "It is not in my power to cause you either harm or good?" 21 Say, "Indeed, there will never protect me from Allah anyone [if I should disobey], nor will I find in other than Him a refuge. 22 Mine is but the publishing from Allah and His messages; and whosoever disobeyeth Allah and His apostle, his portion verily is the Hell-Fire as abiders therein for evermore. 23 (On the Day of Judgment) when the disbelievers witness that with which they have been threatened, they will then know whose helpers are weaker and fewer in number. 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 is) the Knower of the Unseen, and He revealeth unto none His secret, 26 Except whom He has approved of messengers, and indeed, He sends before each messenger and behind him observers 27 that He may know they have delivered the Messages of their Lord; and He encompasses all that is with them, and He has numbered everything in numbers.' 28
