Hadith 5:107
'Abd ibn Sulayman narrated to us, from 'Ubayd Allah, from Nafi', who said: It was found in the will of 'Umar: "Whatever exceeds one hundred and twenty, then in every forty there is a bint labun (a two-year-old female camel), and in every fifty there is a hiqqah (a three-year-old female camel)."
حدثنا عبد بن سليمان عن عبيد الله عن نافع قال وجد في وصية عمر ما زاد على عشرين ومائة ففي كل أربعين بنت لبون وفي كل خمسين حقة
