It is narrated from Sayyiduna Sahl bin Abi Hathmah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) sent his father, Sayyiduna Abu Hathmah (may Allah be pleased with him), as an assessor (kharis, estimating the yield of the fruit). A man came to him (peace and blessings be upon him) and said: "O Messenger of Allah, Abu Hathmah has overcharged me (in the assessment)." So he (peace and blessings be upon him) called Abu Hathmah (may Allah be pleased with him) and said: "Your cousin claims that you have assessed him too much." He said: "O Messenger of Allah, I left out the 'ariyyah dates for (the food of) his household, and what he feeds to the poor, and what (fruit) the wind brings down, (I left that out as well)." So he (peace and blessings be upon him) said: "Your cousin has given you more and has been fair."
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith is narrated from Sayyiduna Sahl bin Abi Hathmah (may Allah be pleased with him) only with this chain, and Ibrahim bin al-Mundhir (may Allah have mercy on him) is alone in narrating it."
