From Sahih Muslim (Hadith 2291):
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
