2216 On the subject of Qisas see
2:178 and the notes thereto. Under the strict limitations there laid down, a life may be taken for a life. The heir is given the right to demand the life; but he must not exceed due bounds, because he is helped by the Law. Some Commentators understand "he" in "he is helped (by the Law)" to refer to the heir of the person against whom Qisas is sought. He too will be helped by the Law, if the heir of the first slain exceeds the bounds of Law.
