1. Muhammad ibn Yahya has narrated from certain persons of our people from al-Hassan ibn Ali ibn Yaqtin from Bakr ibn Muhammad from ‘Aythamah who has said the following: “I once visited abu ‘ Abd Allah عليه السلام, when his women were with him and he (the Imam) sensed a smell and asked what it was. They said, ‘It is a kind of perfume which is placed in one’s hairs.’ He (the narrator) has said, that he (the Imam) commanded to throw it in the sewage.’”
