Is it obligatory to distribute all the meat of Qur'baani animal to the poor if one makes the Qur'baani on behalf of a deceased relative?

Answer

If you are making the Qur'baani with your own funds, it will be permissible to distribute the meat in any way you wish. It is not obligatory to distribute all the meat to the poor. However, if the deceased had made wasiyyat to make Qur'baani on his behalf, and funds from his estate are used to execute the wasiyyat (bequest), then it is Waajib to distribute all the meat to the Fuqara (poor Muslims).
