Appears 3 times in the Quran. (Root: طوع)
  1. And prepare against them what force you can and horses tied at the frontier, to frighten thereby the enemy of Allah and your enemy and others besides them, whom you do not know (but) Allah knows them; and whatever thing you will spend in Allah's way, it will be paid back to you fully and you shall not be dealt with unjustly.

  2. Or do they say: He has forged it? Say: Then bring a chapter like this and invite whom you can besides Allah, if you are truthful.

  3. Or, do they say: He has forged it. Say: Then bring ten forged chapters like it and call upon whom you can besides Allah, if you are truthful.
