Several Children Suckled From the Milk of One Husband and Wife Are Mahram
Issue No. 2118- If a woman suckles several children from the milk of one husband, all of them will be maḥram to one another, and to the woman who has suckled them as well as to her husband. In case a man has more than one wife, and each one of them suckles a child fully, all the children become maḥram to each other as well as to the wives and the husband.
