Musannaf Ibn Abi Shaybah 22399 — A man who buys goods from another

It is narrated from Salim (may Allah have mercy on him) that Sayyiduna Ibn Umar (may Allah be pleased with them both) sold a slave for eight hundred dirhams. The buyer found a defect in the slave and came to Sayyiduna Uthman (may Allah be pleased with him) to dispute it. Sayyiduna Uthman (may Allah be pleased with him) asked Sayyiduna Ibn Umar (may Allah be pleased with them both) about it. He (may Allah be pleased with him) said: "When selling him, I had stated that I am absolved of every defect in him." Sayyiduna Uthman (may Allah be pleased with him) said: "You should swear an oath: 'I sold him the slave, and at the time of sale there was no defect in him that I knew of.'" Sayyiduna Ibn Umar (may Allah be pleased with them both) said: "When selling him, I had stated that I am absolved of every defect in him," and Sayyiduna Ibn Umar (may Allah be pleased with them both) refused to swear the oath. Sayyiduna Uthman (may Allah be pleased with him) had that slave returned to him, and Sayyiduna Ibn Umar (may Allah be pleased with them both) later sold the same slave for fifteen hundred dirhams.
