Isma'il bin Ubaid bin Rifa'ah narrated from his father, who narrated from his grandfather (Rifa'ah), that the Messenger of Allah (peace and blessings be upon him) went towards Baqi', and said: "O assembly of traders!" When they all turned their attention towards him, he (peace and blessings be upon him) said: "Traders will be raised on the Day of Resurrection as wicked ones, except for the one who fears Allah, practices goodness, and speaks the truth."

Imam Darimi (may Allah have mercy on him) said: Abu Nu'aym used to say: 'Ubaidullah bin Rifa'ah, although it is Isma'il bin Ubaid bin Rifa'ah.
