…O ye believers of God! The text of the divine Book is this: If two souls quarrel and contend about a question of the divine questions, differing and disputing, both are wrong. The wisdom of this incontrovertible law of God is this: That between two souls from amongst the believers of God, no contention and dispute may arise; that they may speak with each other with infinite amity and love. Should there appear the least trace of controversy, they must remain silent, and both parties must continue their discussions no longer, but ask the reality of the question from the Interpreter. This is the irrefutable command! 
(‘Abdu’l-Baha, ‘Tablets of the Divine Plan’)
