9:60
إِنَّ مَا ٱل صَّدَقَٰتُ لِ لْ فُقَرَآءِ وَ ٱلْ مَسَٰكِينِ وَ ٱلْ عَٰمِلِينَ عَلَيْ هَا وَ ٱلْ مُؤَلَّفَةِ قُلُوبُ هُمْ وَ فِى ٱل رِّقَابِ وَ ٱلْ غَٰرِمِينَ وَ فِى سَبِيلِ ٱللَّهِ وَ ٱبْنِ ٱل سَّبِيلِ فَرِيضَةً مِّنَ ٱللَّهِ وَ ٱللَّهُ عَلِيمٌ حَكِيمٌ
Zakah expenditures are only for the poor and for the needy and for those employed to collect [zakah] and for bringing hearts together [for Islam] and for freeing captives [or slaves] and for those in debt and for the cause of Allah and for the [stranded] traveler - an obligation [imposed] by Allah. And Allah is Knowing and Wise.
