half of it in common, or he bought half of it, then someone else bought the remainder, and he ate from it, he violates the oath. The disagreement regarding this is as stated previously. If Zayd bought half of it specifically, then mixed it with the other half, and he ate all of it, or more than half, he violates the oath without disagreement; because he certainly ate from what Zayd bought. If he ate half of it, or less than half, there are two views regarding it. The first is that he violates the oath; because it is customary impossible to isolate what Zayd bought from the rest, so the violation is highly apparent. The second is that he does not violate the oath; because the fundamental principle is the absence of violation, and it is not certain that he ate from what Zayd bought. Every situation in which he does not violate the oath, its ruling is the same as one who swears not to eat a date, and it fell into a quantity of dates, and he ate one of them, as we will mention, if Allah Almighty wills. If he ate from food that Zayd bought, then sold it, or bought it for someone else, he violates the oath. It is also possible that he does not violate the oath.

Section: If he swears not to wear anything made from the spinning of so-and-so [a woman], and he wears a garment made from her spinning and the spinning of someone else, he violates the oath. This is the position of al-Shafi'i. If he swears not to wear a garment made from her spinning, [and he wears a garment made from her spinning] and the spinning of someone else, there are two narrations. The first is that he violates the oath, like the previous case. The second is that he does not violate the oath. This is the position of Abu Hanifa and al-Shafi'i, because he did not wear a complete garment made from her spinning. The same applies if he swears not to wear a garment that Zayd wove, or not to eat from a pot he cooked, or not to enter a house he bought, or not to wear a garment that Zayd sewed, and then he wears a garment that he and someone else wove or sewed, or eats from a pot he cooked, or enters a house they both bought; in all these cases, there is the same disagreement and opinion as in the first issue. If he swears not to wear from what Zayd sewed, he violates the oath by wearing a garment that they both sewed; because he wore from what Zayd sewed, unlike if he had said: a garment that Zayd sewed. If he swears not to enter a house belonging to Zayd, and he enters a house belonging to him and someone else, two views have been derived regarding it, and the disagreement regarding it is as has passed.
