Loss of Clothing and Wearing Slippers
Scholars have stated that losing some clothing or household items may indicate facing difficulties with possessions without their complete loss. Wearing slippers (khuffain) may symbolize sea travel, or protection and wealth preservation if worn with a weapon or if new. Conversely, if worn without a weapon or if tight, it could signify severe worries, debts, imprisonment, or restrictions. Wide slippers might point to financial concerns, and old slippers offer weaker protection.
