Bayhaqi 10459 — Evidence that an option of more than three days

Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) said: I heard a man from the Ansar, who had an impediment in his speech, complain to the Prophet (peace and blessings be upon him) about being cheated in sales. He (peace and blessings be upon him) said: "When you transact, say: No deception. Then in whatever goods you buy, you have the option for three days; if you are pleased, keep it, and if you are displeased, return it." Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) said: Now I hear him — whenever he buys any goods, he says: "No deception." There was a stammer in his speech.
(b) Muhammad bin Ishaq (may Allah have mercy on him) said: I narrated this hadith to Muhammad bin Yahya bin Habban (may Allah have mercy on him), and he said: My grandfather was Munqidh bin Amr (may Allah be pleased with him). He had suffered a head wound; his tongue was broken, a stammer came into his speech and his intellect was diminished. He used to be cheated in sales, yet he would not give up trading. He complained to the Prophet (peace and blessings be upon him), and he (peace and blessings be upon him) said: "When you sell goods, say: No deception. Then in every sale you make, you have the option for three nights; if you are pleased, keep it, and if you are displeased, return it."
He lived until the era of Sayyiduna Uthman (may Allah be pleased with him), when he was 130 years old. People became numerous in the era of Sayyiduna Uthman (may Allah be pleased with him). Whenever he bought something and came back with it, people would say to him: Why do you buy? Munqidh bin Amr (may Allah be pleased with him) would say: The Messenger of Allah (peace and blessings be upon him) has given me an option of three days in whatever I buy. People would say: Return it, you have been cheated in the sale. So he would return the goods and say: Take your goods and give me back my dirhams. The seller would say: Take it away; you were satisfied with it. Then, when another Companion (may Allah be pleased with him) passed by, he would say that the Messenger of Allah (peace and blessings be upon him) had given him an option of three days in whatever goods he buys. Then the seller would return his dirhams and take back his goods.
