Why does the money placed in the house decrease despite only I knowing its location?

We advise you to observe the prescribed morning and evening remembrances (adhkar) and protective supplications (ta'awwudhat), as well as before sleeping. Among them is the supplication: "O Allah, I ask You for pardon and well-being in my religion, my worldly life, my family, and my wealth." Reciting Ayat al-Kursi before sleep has the virtue of protecting a person from Satan until morning. Beware of accusing any member of your family without clear proof, and use a safe to keep your money.
