Appears 3 times in the Quran. (Root: سمع)
  1. And how many a generation have We destroyed before them! Do you see any one of them or hear a sound of them?

  2. On that day they shall follow the inviter, there is no crookedness in him, and the voices shall be low before the Beneficent Allah so that you shall not hear aught but a soft sound.

  3. Wherein you shall not hear vain talk.
