Sayyidil Habib Umar bin Hafiz says:

The proper conduct in adopting  a religious path, among any of the accepted paths in the religion, is to know that the existence of other paths manifests the soundness of the sacred law, its vastness, and loftiness. Hence, do not let it be a means for dispute, estrangement, hatred, harshness nor abuse of anyone in order to preserve the honour of another.
