"The face is the principal part of the man by means of which 'X' is distinguished from 'Y' and 'Y' is distinguished from 'Z'. The phrase 'Wajhullah' which literally means 'the face of God' stands for the great 'hadd' (rank) through whom the knowledge of the Unity of God with the knowledge of the angels is acquired in the highest degree. Every one who comes in contact with this 'hadd' (rank) becomes 'baqi'. i.e., eternal and those who deny him become 'fani', i.e., perishable. The holy Prophet says, "I am the face of God and I am the face of my 'ummaat' (community)."
