The Hadith series is based on Bill Warner’s book The Political Traditions of Mohammed – The Hadith for Unbelievers. It is a compilation of all the Hadith (Traditions) related to non-Muslims. The Political Traditions of Mohammed contains both sets of Islamic ethics – one for the Muslim and one for the unbelievers.
Chapter 1 Ethics
The reason for the tax exemption on horses was jihad. Mohammed gave cavalrymen three times the amount he gave foot soldiers from the spoils of war (the wealth of the vanquished) to build a better cavalry.
B2,24,542 Mohammed: “Horses and slaves owned by a Muslim are tax exempt.”
It is forbidden to capture a Muslim and make him a slave. If a slave converts to Islam, then there is a benefit in freeing him. But there is no benefit in freeing a Kafir slave. Islamic slavery is a blessing because sooner or later the slave or the slave’s descendants will convert to Islam in order to be free.
B3,46,693 Mohammed said, “If a man frees a Muslim slave, Allah will free him from the fires of Hell in the same way that he freed the slave.” Bin Marjana said that, after he related that revelation to Ali, the man freed a slave for whom he had been offered one thousand dinars by Abdullah.
