Question: Is it permissible for the person who performs the Adhā sacrifice to give a disbeliever some of the meat from his sacrifice?
It is recommended regarding the Adhā sacrifice to divide its meat into three shares: a third for the person who performed the sacrifice, a third for his friend(s) and a third for the poor people. It is permissible to give a disbeliever some of it due to his poverty or his being a relative or his being a neighbor or to attract his heart to Islam.
