Question I have is one day I was caught by my mum saying I love you to a girl and that we will sleep together. This was after my divorce. My mom was very upset and crying a lot so I didn't understand what to do, now she was tense I was tense and crying trying to calm her down. She then ask me to take kasam on her saying I will not look at any other girls fall in love or have sexual intercourse. We are humans and especially I know I will end up breaking the kasam.

Trying to locate the person one owes money

Q: I took my son to a general practitioner about 5 years ago.

Q: My question is it permissible to have nikah with girl with whose mother I did zina? Now the story is that I did zina with a woman but the reality is that the woman did zina with me because I was 14 and she had three daughters at that time. Now my family did my nikah with her older daughter, she loves me and I love her and we happy for one another. I already did tawbah for what I did and I ask for forgiveness from Allah Almighty. Now we are in relationship already in nikah but I have a question sometimes in my mind, so is it allowed in Islam that her daughter be my lawful wife or I have to leave her?
