Chapter: The sin of one who withholds Zakat
This hadith has been narrated by Zaid b. Aslam with the same chain of transmitters except that he said: None among the owners of camels who does not pay their due, but did not say their due (Zakat) out of them. and he make a mention: He did not miss a single young one out of them. and he said: Their sides. their foreheads and their backs would be cauterised.
