Hadith #3413 (Sunan Abi Dawud) Book: Commercial Transactions (Kitab Al-Buyu) Narrator(s): Ibrahim bin Tahman إبراهيم بن طهمان, Jabir ibn 'Abdullah, Muhammad bin Muslim bin Tadras محمد بن مسلم بن تدرس أبو الزبير, Muhammad bin Sabiq al-Tamimi محمد بن سابق التميمي Grade: Da'if The Prophet (ﷺ) used to send Abdullah ibn Rawahah (to Khaybar), and he would assess the amount of dates when they began to ripen before they were eaten (by the Jews). He would then give choice to the Jews that they have them (on their possession) by that assessment or could assign to them (Muslims) by that assignment, so that the (amount of) zakat could be calculated before the fruit became eatable and distributed (among the people).
