عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ: ((لَيْسَ عَلَى الْمُسْلِمِ فِي فَرَسِهِ وَلَا عَبْدِهِ صَدَقَةٌ))
It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Noble Prophet, peace and blessings be upon him, said: Zakat is not obligatory upon a Muslim for his horse or his slave.
