‘Ubaid b. Rifa'a on his father’s authority reported the Prophet as saying, "The merchants will be raised up on the day of resurrection as evildoers, except those who fear God, are honest and speak the truth.” Tirmidhi, Ibn Majah and Darimi transmitted it, and Baihaqi transmitted it in Shu'ab al-iman on the authority of al-Bara’. Tirmidhi said this is a hasan sahih tradition.
