Maliks Muwatta Book 17, Hadith Number 4.

Section : The Zakat on Gold and Silver Coin.

Yahya related to me from Malik that Muhammad ibn Uqba, the mawla of az Zubayr, asked al-Qasim ibn Muhammad whether he had to pay any zakat on a large sum given to him by his slave to buy his freedom. Al-Qasim said, “Abu Bakr as-Siddiq did not take zakat from anyone’s property until it had been in his possession for a year.”

Al-Qasim ibn Muhammad continued, “When Abu Bakr gave men their allowances he would ask them, ‘Do you have any property on which zakat is due?’ If they said, ‘Yes,’ he would take the zakat on that property out of their allowances. If they said, ‘No,’ he would hand over their allowances to them without deducting anything from them.”
