It was narrated from Abu Hurairah that the Prophet صلی اللہ علیہ وآلہ وسلم said: “Do not go out to meet the riders, and do not bind the udders of camels and sheep. Whoever has bought anything in that manner has two choices: If he wishes he may keep it, or if he wants to return it he may return it, along with a Sa’ of dates.”(Sahih).
