4. Muhammad ibn ’Isma‘il has narrated from al-Fadl ibn Shadhan from Safwan ibn Yahya from Mansur ibn Hazim who has said the following: “I once asked abu ‘Abd Allah , about the case of al-Ta‘widh (protective talisman) which women hang on themselves. He (the Imam) said, ‘Yes, they can do so if it is incased with leather, silver, tube or iron.’”
