It should be clear that it is not correct to give skin to an organization or consortium about which there is a doubt that it is involved in murder or act of vandelization. However, it does not effect the sacrifice itself because the purpose of sacrifice was to shed blood.
In the above mentioned situation, if the skin is given to such an organization then an equivalent amount should be given in Sadaqa
