2,118. Lending Out Her Cloak
Hilchos Issurei Biah 9:29
Let’s say that a woman lends her cloak to a menstruating friend, either Jewish or non-Jewish, and puts it on without examining it first. In such a case, she may ascribe a stain she finds on it to the borrower. The same is true if she lends her cloak to a minor zavah on a day when she’s unclean, to a woman experiencing the pure blood that follows childbirth or to a virgin who is bleeding from her hymen, which is pure blood. In all of these cases, she may attribute the stain to the borrower. However, let’s say that she lends her cloak to a minor zavah on a day that she’s watching or to a major zavah during her seven clean days. In this case, if the lender put it on without examining it and later found a stain, both women are affected because we don’t know from whom the stain originated. If a woman lends her cloak to a friend who is watching herself because she found a stain, she may not ascribe the stain to the borrower because of the rule that we don’t attribute one stain to another.
Hilchos Issurei Biah 9:30
Let’s say that a woman checked her cloak and then herself and she determined that she was clean. Later, she lent that cloak to a friend. If the borrower wore the garment and a stain was found on it when it was returned, the borrower is unclean. The borrower can’t ascribe the stain to the owner, because the owner checked the cloak before lending it.
