Narrated from Rifa’ah (may Allah be pleased with him) that he went out with the Prophet (peace and blessings of Allah be upon him) to the place of Eid. He saw people engaged in buying and selling, so he said:“O assembly of traders!”The people then listened to the Messenger of Allah (peace and blessings of Allah be upon him) and raised their necks and gazes towards him. He said:“Traders will be raised on the Day of Resurrection as sinners, except for the one who fears Allah, does good deeds, and speaks the truth.”__REF_N__ Imam Tirmidhi says:
