Jumay' bin Umayr narrates from his maternal uncle: the Prophet (peace and blessings be upon him) was asked about the most virtuous earning, and he said: "A lawful transaction and a man's earning with his own hand."
Ahmad recorded it, and al-Tabarani recorded it in al-Kabir in abridged form. He stated that it is from his maternal uncle, Sayyiduna Abu Burdah bin Niyar (may Allah be pleased with him), that he
transmitted this report. Al-Bazzar recorded it like Ahmad, except that he said it is transmitted from Jumay' bin Umayr, from his paternal uncle. Abu Hatim declared the narrator Jumay' thiqah (trustworthy), and Imam Bukhari (may Allah have mercy on him) says: "There is room for consideration concerning him (fihi nazar)."
