Chapter : Purification of the skins of the dead animals by tanning them.
The freed slave-girl of Maimuna was given a goat in charity but it died. The Messenger of Allah (may peace be upon him) happened to pass by that (carcass). Upon this be said: Why did you not take off its skin? You could put it to use, after tanning it. They (the Companions) said: It was dead. Upon, this he (the Messenger of Allah) said: Only its eating is prohibited. Abu Bakr and Ibn Umar in their narrations said: It is narrated from Maimuna (may Allah be pleased with her).
