I say, and with God's help: The first condition: They must cover the ankles: and it is not harmful to see the top of the foot; because the relied-upon opinion is that the ankles should be covered from the sides, not from above. The second condition: It must be possible to walk in them for a distance of a farsakh or more — approximately five kilometers — without difficulty, and without wearing anything over them: If one wears a shoe that cannot withstand walking a farsakh and gets torn, it is not permissible to wipe over it, and if one makes a shoe from glass, wood, or iron, it is not permissible to wipe over it. The third condition: They must stay on the feet without being tight; due to their thickness; as thin ones are not suitable for covering the distance. The fourth condition: They must prevent water from reaching the body when wiped over; due to their thickness. The fifth condition: Each of them must be free of a tear that shows three fingers of the smallest toes of the foot according to the correct opinion, not less than that. If the tear is large enough to fit three fingers of the smallest toes and is closed, but opens when walking and shows this amount, then wiping is not permissible, unlike if the tear is large enough to fit three fingers of the smallest toes if inserted, but does not show this amount, then wiping is permissible. The sixth condition: Each of them must be free of many tears under the leg: if each one shows a little, such that if all the visible parts are combined, they equal three fingers, then wiping is prohibited. However, if this amount is in both shoes, then wiping is permissible. The least tear that is considered is one that fits a needle, and anything less than that is not considered; it is treated like a place for stitching. The seventh condition: There must be on each foot from the front of the foot in the shoe the size of three fingers of the smallest fingers of the hand: to have the required amount from the place of wiping, so if he lacks the front of his feet, he cannot wipe over his shoes, even if the heel of the foot is present. The eighth condition: He must wear them while in a state of complete purity at the time of the event after wearing them: it is not a condition that he be in a state of complete purity at the time of wearing the shoes, meaning it is not required that he wear them after completing ablution. If he washed his feet first and then wore his shoes and then completed his ablution before he had an event and then had an event afterwards, it is permissible for him to wipe over the shoes. The ninth condition: The shoe must be occupied at the place of wiping: that he does not wipe over the place empty of the foot if he has lost part of his foot. If the shoe is not occupied at the place of wiping, he cannot wipe; because when he wipes over the place empty of the foot, the wiping does not take place in its proper place, which is the top of the foot, thus it does not prevent the event from reaching the foot. The tenth condition: The event must be light: if the event is heavy — which is menstruation and major ritual impurity — then wiping is not permissible; because the permissibility of wiping in the light event is to avoid hardship; because it is repeated and its occurrence is frequent, leading to hardship and difficulty in removing the shoe, while major ritual impurity does not frequently occur, so it does not lead to hardship in removal. The eleventh condition: The existing purity must not be from dry ablution: meaning it is a condition for the permissibility of wiping that he wears the shoes after being pure by ablution or washing. If he wears them after dry ablution and then finds water, it is not permissible for him to wipe over the shoe, and God knows best.
