It is not permissible to contend with anyone, nor is it acceptable in the sight of God to ill-treat or oppress any soul. Time and again have these sublime words streamed from the Pen of the Most High, blessed and exalted be He: “O ye children of men! The fundamental purpose animating the Faith of God and His Religion is to safeguard the interests and promote the unity of the human race, and to foster the spirit of love and fellowship amongst men. Suffer it not to become a source of dissension and discord, of hate and enmity”. 
(Baha’u’llah, ‘The Tabernacle of Unity, Bahá’u’lláh’s Responses to Mánikchí Sáhib and Other Writings’)
