10-45 (The compiler of the book narrated) that his father - may God be pleased with him - narrated that Muhammad ibn Yahya al-Attar quoted Muhammad ibn Ahmad ibn Yahya ibn Imran al-Ash’ari, on the authority of Sahl ibn Zyad, on the authority of Al-Hussein ibn Yazid, on the authority of Sufyan al-Jariri, on the authority of Abdul-Mumin al-Ansari, on the authority of Abi Ja’far al-Baqir (MGB) that God’s Prophet (MGB) said, “There are ten parts in blessedness. Nine-tenths are in commerce and the next one-tenth is in the skin.”The compiler of the book - may God be pleased with him - asked, “What is meant here by the skin is the skin of sheep. This is certified by another narration which has been cited on the authority of God’s Prophet who said, ‘The nine portions of one’s sustenance comes from commerce and the last part is in the skin - that is the skin of sheep.’”
