The Distinguished Jurists Primer by Ibn Rushd

To whom is it to be paid? They agreed that it is to paid to the poor, because of the saying of the Prophet (God’s peace and blessings be upon him), “Make them free from want on this day”. They disagreed whether it is permissible for the poor of the Ahl al-Dhimma. The majority maintain that it is not permitted for them, while Abu Hanlfa said 'that it is permissible.

The reason for their disagreement is whether the basis for its entitlement is poverty alone, or it is poverty as well as being a Muslim. Those who maintained that it is poverty as well as being Muslim did not permit it for the dhimmiyun, while those who maintained that it is poverty alone permitted it for them.
