Mishkat al-Masabih 6 Zakat كتاب الزكاة 24

وَعَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «لَيْسَ عَلَى الْمُسْلِمِ صَدَقَةٌ فِي عَبْدِهِ وَلَا فِي فَرَسِهِ» . وَفِي رِوَايَةٍ قَالَ: «لَيْسَ فِي عَبْدِهِ صَدَقَةٌ إِلَّا صَدَقَةُ الْفِطْرِ»

Abu Huraira reported God’s messenger as saying, “No sadaqa is due from a Muslim on his slave or his horse.” In a version he said, “There is no sadaqa on his slave except that given at the breaking of the fast.” (Bukhari and Muslim.)
