Appears 3 times in the Quran. (Root: جهر)
  1. And when you said: O Musa! we will not believe in you until we see Allah manifestly, so the punishment overtook you while you looked on.

  2. The followers of the Book ask you to bring down to them a book from heaven; so indeed they demanded of Musa a greater thing than that, for they said: Show us Allah manifestly; so the lightning overtook them on account of their injustice. Then they took the calf (for a god), after clear signs had come to them, but We pardoned this; and We gave to Musa clear authority.

  3. Say: Have you considered if the chastisement of Allah should overtake you suddenly or openly, will any be destroyed but the unjust people?
