al-Rabi' bin Sulaiman الربيع بن سليمان · The Book of Zakah

two men told him, that they came to the Messenger of Allah asking him for charity. He looked from one to the other and he saw that they were strong. The Messenger of Allah said: "If you want, I will give you, but no rich man or one who is strong and able to earn has a share of it."
