Surah Al-Kahf (The Cave), Verse 26

قُلِ اللّٰهُ اَعْلَمُ بِمَا لَبِثُوْا لَهٗ غَیْبُ السَّمٰوٰتِ وَالْاَرْضِ اَبْصِرْ بِهٖ وَاَسْمِعْ مَا لَهُمْ مِّنْ دُوْنِهٖ مِنْ وَّلِیٍّ وَّلَا یُشْرِكُ فِیْ حُكْمِهٖۤ اَحَدًا ۟

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.”
