Al-Hakam ibn Uyaynah said that he went along with some people to Abdullah ibn Ukaym, a man of Juhaynah. al-Hakam said: They entered and I sat at the door. Then they came out and told me that Abdullah ibn Ukaym had informed them that the Messenger of Allah ﷺ had written to Juhaynah one month before his death: Do not make use of the skin or sinew of an animal which died a natural death. Abu Dawud said: Al-Nadr bin Shumail said: The skin is called ihab when it is not tanned and when it is tanned, it not called ihab but na, es shann and qirbah (tanned skin or leather).

Narrated Abdullah ibn Ukaym: The letter of the Messenger of Allah ﷺ was read out to us in the territory of Juhaynah when I was a young boy: Do not make use of the skin or sinew of an animal which died a natural death.
