Wiping off impurity on a shoe
Q: A couple of years ago, I messed my sisters shoe with some impurities and I just wiped it off. She uses that shoe for wudhu. Now later in my life I'm regretting not telling her at the time/washing the impurities off. Since she puts her wet foot in the shoe, her foot will become dirty. She doesn't know anything about this. Are all her Salaahs accepted? Will I be responsible for all her Salaahs not being accepted and will I have to pay her for all those Salaahs in the Aakhira? I don't know whether she still uses that shoe. I'm very remorseful and worried about this. What should I do?
