Ibn Mas'ud reported God’s Messenger as saying, “If anyone swears a firm oath, 1 acting wickedly thereby, and appropriates by it property belonging to a Muslim, God will be angry when he meets Him on the day of resurrection.” And God has sent down the verification of that, “Those who barter for a small price God's covenant and their oaths”2. (Bukhari and Muslim.) 1. Or an oath he is compelled to take. 2. Al-Qur’an, 3:77
