Say: 'I call only upon my Lord, and I do not associate with Him anyone. 20 Say, "Indeed, I do not possess for you [the power of] harm or right direction." 21 Say: “None can protect me from Allah, nor can I find a refuge apart from Him. 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 [Let them, then, wait] until the time when they behold that [doom] of which they were forewarned: for then they will come to understand which [kind of man] is more helpless and counts for less! 24 Say: "I do not know if what is promised you is near, or if my Lord prolongs its term. 25 [He is] Knower of the unseen, and He does not disclose His [knowledge of the] 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 That He may know that they have indeed conveyed the messages of their Lord. He surroundeth all their doings, and He keepeth count of all things. 28
