Bahz bin Hakeem reported,

My father related to me from my grandfather, who said, I heard the Prophet ﷺ say, "Concerning every herd of grazing camels, for every forty there is a two-year-old female camel due as zakat. The camels are not to be separated from their proper count. Whoever gives it willingly seeking reward will be rewarded for it, and whoever refuses, we will take it from him along with half of his camels, as a firm decree from the decrees of our Lord. None of it is lawful for the family of Muhammad ﷺ."

عن بهز بن حكيم، قال

حدثني أبي، عن جدي، قال: سمعت النبي ﷺ يقول: في كل إبل سائمة في كل أربعين ابنة لبون، لا يفرق إبل عن حسابها من أعطاها مؤتحرا فله أجرها ومن أبي فإنا آخذوها وشطر إبله عزمة من عزمات ربنا، لا يحل لآل محمد ﷺ منها شيء.
