قُلِ ٱللَّهُ أَعۡلَمُ بِمَا لَبِثُواْۖ لَهُۥ غَيۡبُ ٱلسَّمَٰوَٰتِ وَٱلۡأَرۡضِۖ أَبۡصِرۡ بِهِۦ وَأَسۡمِعۡۚ مَا لَهُم مِّن دُونِهِۦ مِن وَلِيّٖ وَلَا يُشۡرِكُ فِي حُكۡمِهِۦٓ أَحَدٗا

Qulil laahu a'lamu bimaa labisoo lahoo ghaibus samaawaati wal ardi absir bihee wa asmi'; maa lahum min doonihee minw waliyyinw wa laa yushriku fee hukmihee ahadaa

Say: "Allah knows best how long they stayed: with Him is (the knowledge of) the secrets of the heavens and the earth: how clearly He sees, how finely He hears (everything)! They have no protector other than Him; nor does He share His Command with any person whatsoever.

— Al-Kahf (ٱلْكَهْف), 18:26
