Yahya related to me from Malik from Abdullah ibn Umar from Sulayman ibn Yasar from Irak ibn Malik from Abu Hurayra that the Messenger of Allah, may Allah bless him and grant him peace, said, "A muslim does not have to pay any zakat on his slave or his horse".
Zakat is an important pillar in Islam which helps the needy by providing them with financial assistance so they can live a better life. It is a form of charity which helps those who cannot afford basic necessities such as food and clothing. By exempting Muslims from having to pay zakat on their slaves or horses, it shows how much importance was placed upon taking care of one's own finances while still being generous towards others in need at the same time.
This hadith teaches us the importance of being mindful with our finances while still helping those who are less fortunate than ourselves through charity work such as giving out zakats or donations when possible. It also reminds us that animals should be treated kindly since they too are part of Allah's creation and deserve love and respect just like humans do!
