In a dream it signifies standing up for the religion or for one's fathers and mothers, and protective jealousy over one's wife. If a person joins the party of the rebels, it is feared that he will apostatize from Islam, or go against the religion, or throw off obedience to one whom he must obey, or abandon the prayer.
