(Rahma). Mercy and compassion. There are two kinds of mercy. The first is an essential mercy or the mercy of free-gift which Allah bestows upon all creatures without distinction. The second is a specific mercy or the mercy of obligation which Allah gives to those slaves who are deserving of it. When the slave has been blessed with the 'opening of unveiling' he sees, smells, tastes, touches and hears Allah's Rahma, which not only surrounds him, but also penetrates every atom of his being.
