Prohibition of Deception in Sales

Question: We work in raising livestock and trading in it, and sometimes some of the sheep or camels get sick, so we sell them in the markets while they are afflicted with that disease. Do we have any obligation regarding this?

Answer: Buying and selling are among the things Allah the Exalted has made permissible for His servants, and they are the foundation of their interests and benefits. However, buying and selling must be based on truthfulness, trustworthiness, and sincere advice.The Prophet (peace and blessings be upon him) said:, and the Prophet (peace and blessings be upon him) forbade deception,And he said: ،And he said:, and there are many hadiths on this matter. If you sell a commodity that has a defect, it is obligatory for you to disclose it to the buyer, and you must not conceal it or deceive him about it. Therefore, these sheep that you are selling, which have a disease, you must disclose the disease they have, and sell them as defective, and inform the buyer of what is in them, so that your sale is based on truthfulness and not concealment.
