Anas said that God’s Messenger offered for sale a saddle-cloth (woolen cloth placed on a camel under the pack-saddle), and a drinking-vessel, saying, “Who will buy this saddle-cloth and drinking- vessel?” A man offered to take them for a dirham and the Prophet asked whether anyone would give more. A man offered him two dirhams and he sold them to him.
Narrated Al-‘Adda’ b. Khalid b. Haudha brought out a document to this effect:
This is what al-‘Adda’ b. Khalid b. Haudha brought from Muhammad, God’s Messenger. He bought from him a slave, or a slave woman, with no disease or wickedness, or anything unlawful*, a transaction between two Muslims.
Tirmidhi transmitted it, saying this is a gharib tradition.
* This might be bad character on the part of the slave or unlawful enslavement.
Wathila b. al-Asqa' told that he heard God's Messenger say, "If anyone sells a defective article without drawing attention to it, he will remain under God’s anger," or, “the angels will continue to curse him.”
Ibn ‘Umar said he used to sell camels at an-Naqi‘for dinars and take dirhams for them, and sell for dirhams and take dinars for them. He went to the Prophet and mentioned that to him, and he replied, “There is no harm in taking them at the current rate so long as you do not separate leaving something still to be settled.”
Tirmidhi, Abu Dawud, Nasa’i and Darimi transmitted it.
