The reason for this, in addition to the existence of perfection, is that the ruling belongs to the owner of the time, which is the ruling that is abrogated, and he is the living, and the ruling that is abrogated is the dead person, so immediately there is a ruler, and if the one who made it falls short of the degree of perfection, then he has authority over the perfect, so how come when he is perfect, the abrogation is for him, like death, so he acts on his behalf in purifying him, for if he were alive, he would purify himself. Just as if the perfect person was revealed to him what he lacked, you would work to achieve it, and so is the ruling on someone who falls short of the level of perfection on the path .
