Narrated Abdullah ibn Ukaym,: 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 Apostle of Allah (peace_be_upon_him) 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.
