Narrated Abu Hurairah: "The Prophet (ﷺ) prohibited meeting the goods being brought (to the market). If someone were to meet them and buy them, then the owner of the goods retains the option when he reaches the market." [Abu 'Eisa said:] This Hadith is Hasan Gharib narration of Ayyub (a narrator). The Hadith if Ibn Mas'ud is a Hasan Sahih Hadith. There are those among the people of knowledge who disliked meeting the owners of the goods, saying that it is a type of deception.
