They purchase goods from them before they arrive at the markets, and sometimes they deceive them with a clear deception, thereby harming them. Sometimes they also harm the people of the city; for when the caravans arrive, they would have sold their goods, while those who met them do not sell them quickly and instead wait for the price to rise. It is thus in the same category as a resident selling on behalf of a traveler, so the Prophet (peace and blessings of Allah be upon him) forbade it. Tawus narrated from his father from Ibn Abbas, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "Do not meet the caravans, and let not a resident sell on behalf of a traveler." A similar account is narrated from Abu Hurayrah, and both are agreed upon (2). Most scholars of knowledge disliked this, including Umar ibn Abd al-Aziz, Malik, al-Layth, al-Awza'i, al-Shafi'i, and Ishaq. It was narrated from Abu Hanifah that he saw no harm in it. However, the Sunnah of the Messenger of Allah (peace and blessings of Allah be upon him) is more deserving of being followed. If one contradicts this, meets the caravans, and purchases from them, the sale is valid according to the view of everyone. Ibn Abd al-Barr stated this. Another report was narrated from Ahmad stating that the sale is invalid due to the manifest nature of the prohibition. The first view is more correct, because Abu Hurayrah narrated that the Messenger of Allah (peace and blessings of Allah be upon him) said: "Do not meet the goods imported for sale; whoever meets them and purchases from them, then when he arrives at the market, he has the option [to rescind]." Recorded by Muslim (3), and the option [of rescission] exists only in a valid contract. Furthermore, the prohibition is not due to a reason inherent in the sale, but rather it relates to a type of deception that can be remedied by establishing an option [to rescind], thus it resembles the sale of a musarrah (animal whose milk has been withheld in the udder to deceive the buyer), and it differs from a resident selling for a traveler, for that cannot be remedied by an option [to rescind], as the harm is not upon him, but rather upon the Muslims. When this is established, the seller has the option if he learns that he has been deceived. The scholars of opinion said: He has no option. Yet we have narrated the statement of the Messenger of Allah (peace and blessings of Allah be upon him) regarding this, and no one's statement carries weight alongside his. The manifest view of the school (Madhhab) is that he has no option unless there is deception.
