The most blessed word to say.
It comes from God.
God is the peace and from him comes the peace.
He is free from every single imperfection and every adversary.
It is him who frees us from adersaries.
It is him who cleans and guides our hearts.
He is the peace.
He brings the peace into our lives.
Islam is one community and we must all respect eachother because God loves those who bring peace between eachother.
