It is narrated from Sayyiduna Abdur Rahman bin Mas'ud bin Niyar (may Allah be pleased with him) that Sayyiduna Sahl bin Abi Hathmah (may Allah be pleased with him) came to our gathering and narrated a hadith that the Noble Prophet (peace and blessings be upon him) said: "When you estimate (the fruits on the trees), then take (two-thirds) and leave one-third; if not one-third, then leave one-fourth."
