Hadith 5:92
Waki’ narrated to us, from Sufyan, from Musa ibn ‘Uqbah, from Nafi’, from Ibn ‘Umar, who said: ‘Umar said: "When the camels become numerous, then in every fifty there is a hiqqah (a camel in its fourth year), and in every forty there is a bint labun (a camel in its third year)."
حدثنا وكيع عن سفيان عن موسى بن عقبة عن نافع عن بن عمر قال قال عمر إذا كثرت الإبل ففي كل خمسين حقة وفي كل أربعين بنت لبون
