﴿قُلِ اللَّهُ أَعْلَمُ بِمَا لَبِثُوا ۖ لَهُ غَيْبُ السَّمَاوَاتِ وَالْأَرْضِ ۖ أَبْصِرْ بِهِ وَأَسْمِعْ ۚ مَا لَهُم مِّن دُونِهِ مِن وَلِيٍّ وَلَا يُشْرِكُ فِي حُكْمِهِ أَحَدًا﴾
[ الكهف: 26]

18:26 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."

Say - O Messenger: Allah knows best about how long they remained in the cave and He has told us about the period they remained there.
No statement can be considered after Allah’s, may He be glorified.
To Him alone, may He be glorified, belongs everything hidden in the heavens and on earth.
He created and knows all of it.
How well He sees! May He be glorified! He sees everything.
How well He hears! He hears everything.
They have no one to take charge of their matter besides Him.
He does not share His rule with anyone.
He alone passes judgement.

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."
