Say: "I call on my Lord alone and I do not associate any one with Him." 20 Say, "I do not possess any power to harm or benefit you". 21 Say: 'None shall protect me from Allah, and other than Him, I will find no refuge, 22 But [I have for you] only notification from Allah, and His messages." And whoever disobeys Allah and His Messenger - then indeed, for him is the fire of Hell; they will abide 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 The Knower of the unseen! so He does not reveal His secrets to any, 26 Save unto every messenger whom He hath chosen, and then He maketh a guard to go before him and a guard behind him 27 so as to make manifest that it is indeed [but] their Sustainer's messages that these [apostles] deliver: for it is He who encompasses [with His knowledge] all that they have [to say,] just as He takes count, one by one, of everything [that exists]. 28
