40. Ali ibn Ibrahim has narrated (from his father) from Harun ibn Muslim from Mas’adah ibn Sadaqah who has said the following: “I once heard abu ‘Abd Allah , saying, ‘All things are lawful for you until you recognize it to be exactly an unlawful item which you must avoid from your own side. One such example is a cloth which you may have purchased and it is proved a stolen cloth; or a slave who is with you and perhaps he is free who has sold himself or is tricked and sold or is compelled; or a woman whom you have married and she is your sister or is one who is fed with milk from your wife or mother or sister or daughter and things likewise; until it becomes clear that they are otherwise or testimony proves otherwise.’”
