خَفِىّ

Appears 2 times in the Quran. (Root: خفي)
  1. When he called upon his Lord in a low voice,

  2. And you shall see them brought before it humbling themselves because of the abasements, looking with a faint glance. And those who believe shall say: Surely the losers are they who have lost themselves and their followers on the resurrection day. Now surely the iniquitous shall remain in lasting chastisement.
