A Non-Muslim asked a Muslim: why do your women cover their bodies and hair?
The Muslim smiled and got two sweets he opened the first one and kept the other one closed. He threw them both on to the dusty floor and asked the Non-Muslim if I ask you to pick one out of these two sweets which would you pick?
The Non Muslim replied: the covered one
Then the Muslim said: in the same way that the wrapper protected its sweet from the dust the hijab protects our ladies from the sins and bad of this world.
