Abdullah bin Umar reported,

The Messenger of Allah ﷺ wrote a document concerning zakat but did not send it out to his agents before he passed away. He kept it attached to his sword. When he died, Abu Bakr acted upon it until he passed away, then Umar acted upon it until he passed away.It contained the following, for every five camels, one sheep is due, for ten, two sheep, for fifteen, three sheep, for twenty, four sheep, and for twenty-five, a one-year-old female camel.My father said, "Then an illness came upon me while I was in the gathering of Abbad bin Awwam, so I wrote down the rest of the hadith. I think I did not properly grasp some of it, so I became uncertain about the remaining portion of the hadith and left it out."

حدثنا عباد بن العوام حدثنا سفيان بن حسين عن الزهري عن سالم

عن ابن عمر

أن رسول الله ﷺ كتب كتاب الصدقة فلم يخرجه إلى عماله حتى قبض فقرنه بسيفه فلما قبض عمل به أبو بكر رضي الله عنه حتى قبض ثم عمر حتى قبض فكان فيه في خمس من الإبل شاة وفي عشر شاتان وفي خمس عشرة ثلاث شياه وفي عشرين أربع شياه وفي خمس وعشرين ابنة مخاض قال أبي ثم أصابتني علة في مجلس عباد بن العوام فكتبت تمام الحديث فأحسبني لم أفهم بعضه فشككت في بقية الحديث فتركته
