Hunting & Slaughtering

Narrated Salama bin Al-Aqwa' (Radi-Allahu 'anhu):

In the evening of the day of the conquest of Khaibar, the army made fires
(for cooking). The Prophet (Sallallahu 'Alaihi Wa Sallam) said, "For what
have you made these fires?" They said, "For cooking the meat of domestic
donkeys." He said, "Throw away what is in the cooking pots and break the
pots." A man from the people got up and said, "Shall we throw the contents
of the cooking pots and then wash the pots (instead of breaking them)?" The
Prophet (Sallallahu 'Alaihi Wa Sallam) said, "Yes, you can do either'
