Silsilah as-Sahihah 1138 — Why is a trader sinful?

Sayyiduna Bara’ bin Azib (may Allah be pleased with him) says: The Messenger of Allah (peace and blessings be upon him) came to us in Baqi‘ and said: “O assembly of traders!” They stretched their necks and looked. Then the Prophet (peace and blessings be upon him) said: “Indeed, on the Day of Resurrection, traders will be raised as wicked people, except for the one who feared Allah, did good deeds, and spoke the truth.”
