[Machine] Zakat is not in the wealth of the slave nor the properties.  

لَيْسَ فِي مَالِ الْعَبْدِ وَلَا الْمُكَاتَبِ زَكَاةٌ  

[Machine] There is no obligation to pay zakat from the wealth of employees or slaves until they are set free. This was narrated in the context of employees from Abdullah ibn Bazīʿ, from Ibn Jurayj, as a raised narration, but he is weak. The authentic narration is attributed to Masruq, Sa'id ibn al-Musayyib, Sa'id ibn Jubayr, 'Ata', and Mak'hool.  

لَيْسَ فِي مَالِ الْمُكَاتَبِ وَلَا الْعَبْدِ زَكَاةٌ حَتَّى يُعْتَقَ وَرُوِيَ ذَلِكَ فِي الْمُكَاتَبِ عَنْ عَبْدِ اللهِ بْنِ بَزِيعٍ عَنِ ابْنِ جُرَيْجٍ مَرْفُوعًا وَهُوَ ضَعِيفٌ وَالصَّحِيحُ مَوْقُوفٌ وَهُوَ قَوْلُ مَسْرُوقٍ وَسَعِيدِ بْنِ الْمُسَيِّبِ وَسَعِيدِ بْنِ جُبَيْرٍ وَعَطَاءٍ وَمَكْحُولٍ
