4. A number of our people have narrated from Sahl ibn Ziyad from Ayyub ibn Nuh in a marfu‘ manner who has said the following
“Abu ‘Abd Allah (a.s.), has said, ‘If a piece is cut from a man, it is dead. In case of one’s touching, whatever piece has bone in it Ghusl (bath) becomes obligatory, if bone is not found in it, Ghusl (bath) is not obligatory.’”
