Touching one's mother in-law with lust
Q: An accident occurred in bus journey some years ago, that is: my mother in law's seat was beside my seat. She was feeling ill because of some illness but I was feeling lust/desire but not highly exited. Then I probably touch her (not her private part). But I was mentally addicted by shaitan’s waswasa. She didn't know this was my situation. I had no idea before about marriage, mahrams and hurmat-e-mushara. After I came to know about hurtmat-e-musaahara, I repented and made Towba to Allah Ta'ala. Now I am very alert about shaitan’s waswasa. But mentally I am worried about that accident. Now my wife would be lawful? I have one daughter. Please clearly advise me.
