Say, [O Muhammad], "I only invoke my Lord and do not associate with Him anyone." 20 Say: "Neither is your loss within my power nor bringing you to guidance." 21 Say, "Surely no one can protect me against God, nor can I find besides Him any place of refuge. 22 (Mine is) but conveyance (of the Truth) from Allah, and His messages; and whoso disobeyeth Allah and His messenger, lo! his is fire of hell, wherein such dwell for ever. 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 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 Except whom He has approved of messengers, and indeed, He sends before each messenger and behind him observers 27 That he may know that they have conveyed the messages of their Lord; and He has encompassed whatever is with them and has enumerated all things in number. 28
