I heard the Messenger of Allah ﷺ say, "For every forty grazing camels, a two-year-old female camel is due. The camels are not to be separated from their count. Whoever gives it seeking reward, will have its reward, and whoever withholds it, we will take it from him along with half of his camels, as a binding decree from the decrees of our Lord . None of it is lawful for the family of Muhammad."
حدثنا يحيى بن سعيد حدثنا
سمعت رسول الله ﷺ يقول في كل إبل سائمة في كل أربعين ابنة لبون لا تفرق إبل عن حسابها من أعطاها مؤتجرا فله أجرها ومن منعها فإنا آخذها وشطر إبله عزمة من عزمات ربنا تبارك وتعالى لا يحل لآل محمد منها شيء
