Muhammad bin Ja'far bin Abi Kathir محمد بن جعفر بن أبي كثير · The Book of Zakah

The Messenger of Allah said: "No Sadaqah is due on less than five Awaq."

"The best of charity is that which is given when you are self-sufficient, and the upper hand is better than the lower hand, and start with those for whom you are responsible."
