"On the other hand, Allah directs man to the spiritual purity through the act of giving that is represented by charity that the pious pays as "Zakat" and "Sadakat" almsgiving, and other financial obligations."
Allah's Apostle said, "There is no Zakat either on a horse or a slave belonging to a Muslim"
These are the orders issued by the creature of Allah, Ali, the son Abu Taalib (a) to Maalik, the son of Ashtar when he appointed Maalik as the Governor of Egypt to collect Zakat there, to combat the enemies of Islam and Egypt, to work for the welfare of its people and to look after its prosperity.
Allah's Apostle said, "There is no Zakat either on a horse or a slave belonging to a Muslim".Abu Huraira
It has been narrated on the authority of Abdullah b. 'Umar that the Messenger of Allah said: I have been commanded to fight against people till they testify that there is no god but Allah, that Muhammad is the messenger of Allah, and they establish prayer, and pay Zakat and if they do it, their blood and property are guaranteed protection on my behalf except when justified by law, and their affairs rest with Allah.
( Zakat ) charity is only for the poor and the needy, and those employed to administer it, and those whose hearts are made to incline (to truth), and (to free) the captives, and those in debt, and in the way of Allah and for the wayfarer -- an ordinance from Allah. And Allah is Knowing, Wise.
