It was narrated that Suwaid bin Ghafalah said: "The Zakah collector of the prophet came to us, and I went to him, sat with him, and heard him say: In my contract it says that we should not take any sucking young, nor combine what is separate, nor separate what is combined.' A man brought a she-camel with a big hump to him and said: 'Take it, but he refused." (Daif)
