Using animal's dead skin

Narrated 'Abdullah bin 'Abbas (Radi-Allahu 'anhu):

Once Allah's Apostle (Sallallahu 'Alaihi Wa Sallam) passed by a dead sheep
and said to the people, "Wouldn't you benefit by its skin?" The people
replied that it was dead. The Prophet (Sallallahu 'Alaihi Wa Sallam) said,
"But its eating only is illegal."
