I might says that the light is a metaphor of our religion,
Islam is my religion and Islam is your religion.
and Islam is our religion.
there is no perfect religion except it.
Without religion, our life is like a kite without rope.
It will fly without any directions.
But if you have Allah, and you follow all the Islam's rules.
Than you will be guided to the right destination.
The right direction.
Islam is the religion that will gives us the light.
It is our instructor.
