Does entering a house while riding fulfill an oath not to place one's foot inside it?

Fulfillment of an oath not to place one's foot inside a dwelling (Dar) occurs if the person enters it, whether walking or riding, with or without footwear. This position is held by the Ashab al-Ra'y (People of Opinion/Jurists who rely on reasoning). The rationale is that the person has indeed entered the dwelling, which is equivalent to entering on foot. Furthermore, the foot is considered placed within the dwelling because it rests upon the animal being ridden, thus resembling entering while wearing shoes.

Abu Thawr stated that if one enters while riding, the oath is not broken because the foot itself was not placed inside the dwelling. This view is countered by asserting that if the riding action is commonly understood in customary usage (Urf) to mean avoiding entry, the oath must be interpreted based on that customary meaning, as widely known metaphorical terms become accepted conventional names.
