Sura al-Naml 27:65

قُل لَّا يَعْلَمُ مَن فِى ٱلسَّمَٰوَٰتِ وَٱلْأَرْضِ ٱلْغَيْبَ إِلَّا ٱللَّـهُ وَمَا يَشْعُرُونَ أَيَّانَ يُبْعَثُونَ

qul lā yaʿlamu man fī l-samāwāti wa-l-arḍi l-ghayba illā allāhu wa-mā yashʿurūna ayyāna yubʿathūna

Say: None in the heavens or on earth, except Allah, knows what is hidden: nor can they perceive when they shall be raised up (for Judgment).
