رَأْسهِمْ

Appears 3 times in the Quran. (Root: راس)
  1. Hastening forward, their heads upraised, their eyes not reverting to them and their hearts vacant.

  2. Then they were made to hang down their heads: Certainly you know that they do not speak.

  3. And could you but see when the guilty shall hang down their heads before their Lord: Our Lord! we have seen and we have heard, therefore send us back, we will do good; surely (now) we are certain.
