(72:25) Say, "I do not know if what you are promised is near or if my Lord will grant for it a [long] period." (72:26) [He is] Knower of the unseen, and He does not disclose His [knowledge of the] unseen to anyone (72:27) Except whom He has approved of messengers, and indeed, He sends before each messenger and behind him observers (72:28) 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.
