Hadith 5:104
'Abbad ibn al-'Awwam narrated to us, from Sufyan ibn Husayn, from al-Zuhri, from Salim, from Ibn 'Umar: That the Prophet, peace and blessings of Allah be upon him, wrote the document of Zakat and attached it to his sword, or he said: to his will. He did not bring it out until he passed away. Abu Bakr acted upon it until he perished, then 'Umar acted upon it until he perished. It contained: Regarding camels, if they exceed one hundred and twenty, then for every fifty there is a hiqqah (a three-year-old camel), and for every forty there is a bint labun (a two-year-old camel).
حدثنا عباد بن عوام عن سفيان بن حسين عن الزهري عن سالم عن بن عمر أن النبي صلى الله عليه وسلم كتب كتاب الصدقة فقرنه بسيفه أو قال بوصيته فلم يخرجه حتى قبض فعمل به أبو بكر حتى هلك ثم عمل به عمر حتى هلك فكان فيه في الإبل إذا زادت على عشرين ومائة ففي كل خمسين حقة وفي كل أربعين بنت لبون
