Say: "I invoke my Sustainer alone, for I do not ascribe divinity to anyone beside Him." 20 Say, "It is not in my power to cause you either harm or good?" 21 Say, "Surely no one can protect me against God, nor can I find besides Him any place of refuge. 22 My duty is only to convey that which I receive from Him and His messages." For those who disobey God and His Messenger there is the fire of hell, wherein they will abide forever. 23 At length, when they see (with their own eyes) that which they are promised,- then will they know who it is that is weakest in (his) helper and least important in point of numbers. 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 is the Knower of the Unseen and does not disclose His Unseen to anyone, 26 Other than an apostle He has chosen, when He makes a sentinel walk in front of him and a sentinel behind, 27 So that He may know if they have delivered their Lord's messages. He comprehends all that has been given them, and keeps count of everything. 28
