مسائل المنتخبه (Articles Of Islamic Acts) - الخوئي، السيد أبوالقاسم - الصفحة ٢٧ - HOW A PURE THING BECOMES IMPURE

remaining part will remain pure. Same is the case with a melon, cucumber etc.
١٣٠. When syrup or oil (ghee) is in such a condition that if some quantity of it is removed their space does not remain vacant, theî entire quantity, will becomeimpure immediately when even theî slightest part becomes impure. But if, after taking out some quantity, a part of such a thing becomes vacant, only that part of it willbecome impure which has acquired impurity, even though the space which becomes vacant is filled up later. Hence, if the excreta of a rat falls on it, only that portion willbecome impure on which the excreta has fallen and the rest will remain pure.
١٣١. If a fly or an insect sits on an impure thing which is wet and later sits on a pure thing which is also wet the pure thing will become impure if one knows thatthe insect was carrying impurity with it, but it will remain pure if one does not know this.
١٣٢. If a part of ones body which is perspiring, becomes impure, all those parts to which the sweat reaches, will become impure and the rest of the body willremain pure.
١٣٣. If there is blood in the phlegm or substance which comes out of the nose or throat the place where there is blood in it will be impure and the remaining partwill be pure. Hence, if these substances reach outside the throat or nose the part about which one is sure that the impure place of the substance has reached it is impure andthe part about which one is doubtful whether or not the impure place of the substance has reached it is pure.
١٣٤. If an ewer or a vessel which has a hole in its bottom is placed on impure earth and its water ceases to flow and the water which collects under it gets mixedwith the water in the ewer the water inside the ewer will become impure. However, if the water inside the ewer continues to flow it will not become impure.
