كتاب الزكاة
Read the English translation first, with the original Arabic directly underneath.
It was narrated that Abu Hurairah said:
"The Messenger of Allah said: 'A Muslim man does not have to pay Zakah on his slave or his horse."'
لاَ زَكَاةَ عَلَى الرَّجُلِ الْمُسْلِمِ فِي عَبْدِهِ وَلاَ فَرَسِهِ
