Zakāh expenditures are only for the poor and for the needy and for those employed for it and for bringing hearts together [for Islām] and for freeing captives [or slaves] and for those in debt and for the cause of Allāh and for the [stranded] traveler - an obligation [imposed] by Allāh. And Allāh is Knowing and Wise.
And among them are those who abuse the Prophet and say, "He is an ear." Say, "[It is] an ear of goodness for you that believes in Allāh and believes the believers and [is] a mercy to those who believe among you." And those who abuse the Messenger of Allāh - for them is a painful punishment.
