Translation of the verse 26 from Surah Al-Kahf : Number of verses 110 - - page 296 - Part 15.
Say: "Allah knows best how long they stayed. With Him is (the knowledge of) the unseen of the heavens and the earth. How clearly He sees, and hears (everything)! They have no Wali (Helper, Disposer of affairs, Protector, etc.) other than Him, and He makes none to share in His Decision and His Rule."
Say, "Allah is most knowing of how long they remained. He has [knowledge of] the unseen [aspects] of the heavens and the earth. How Seeing is He and how Hearing! They have not besides Him any protector, and He shares not His legislation with anyone."
(18:26) (to the reckoning of the period). O Prophet, say, "Allah knows best about the period of their stay there, for He is fully aware of all that is hidden in the heavens and the earth." What an excellent Seer and Hearer He is! There is no other guardian of the creation in the heavens and the earth, and He does not associate anyone with Himself in His authority.
