When the husband accuses his wife of adultery or rejects a particular child as being his own child, then both the husband and wife have to go to a Shar’î judge. The judge will ask both of them to take an oath. First, the husband will take the following oath: “I make Allah my witness and say that I am speaking the truth with regard to the act for which I have accused her.” He should take this oath four times. The fifth time he must say: “If I am lying, may Allah’s curse descend upon me.”
When the husband completes this, the wife must say the following four times: “I make Allah my witness and say that he is lying with regard to the act for which he is accusing me of.” The fifth time she must say: “If he is truthful in this accusation, may the wrath of Allah descend upon me.”
Once both of them take this oath, the judge will separate them and one talâqul bâ’in will take place. The child will not be attributed to this husband, but will be given in the care of the mother. In the Sharî‘ah, this oath and counter-oath is known as li’ân.
