Surah An-Naml (The Ants), Verse 65

قُلْ لَّا یَعْلَمُ مَنْ فِی السَّمٰوٰتِ وَالْاَرْضِ الْغَیْبَ اِلَّا اللّٰهُ وَمَا یَشْعُرُوْنَ اَیَّانَ یُبْعَثُوْنَ ۟

Qul laa ya'lamu man fis sammaawaati wal ardil ghaiba illal laah; wa maa yash'uroona aiyaana yub'asoon

“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).”
