“Allah, the Most Blessed, the Most High, said to Jesus, son of Mary (a.s.), ‘O Jesus, your tongue must be one tongue in private and in public so also must be your heart. I warn you against your own soul and Myself am a sufficient expert over your (activities). Two tongues are not proper for one mouth just as two swords are not proper in one sheath or two hearts in one chest, and so also are minds.’”
