Appears 11 times in the Quran. (Root: جنن)
  1. And they say: O you to whom the Reminder has been revealed! you are most surely insane:

  2. Said he: Most surely your Messenger who is sent to you is mad.

  3. And to say: What! shall we indeed give up our gods for the sake of a mad poet?

  4. Yet they turned their backs on him and said: One taught (by others), a madman.

  5. But he turned away with his forces and said: A magician or a mad man.

  6. Thus there did not come to those before them a messenger but they said: A magician or a mad man.

  7. Therefore continue to remind, for by the grace of your Lord, you are not a soothsayer, or a madman.

  8. Before them the people of Nuh rejected, so they rejected Our servant and called (him) mad, and he was driven away.

  9. By the grace of your Lord you are not mad.

  10. And those who disbelieve would almost smite you with their eyes when they hear the reminder, and they say: Most surely he is mad. Those who disbelieved show their ridicule in their eyes when they hear the message and say, "He is crazy!"

  11. And your companion is not gone mad.
