Losing one's wedding ring

Q: I am a married Muslim woman. I have lost my ring which I got as a gift on my nikaah from my husband just like an engagement ring for which I am very upset but people around me told us that losing your nikaah ring isn't a good sign for married life.

I am very much tensed and I wish that this is just a rumor, nothing else. Please tell me about it in the light of islam.

Claiming from one's mother's estate after helping pay for her hospital bill

Q: Upon the death of my mother (at a Dubai hospital) we had to settle the bill at the hospital for the release of her body. I acompanied my father and my brother to the Dubai hospital and when the bill was produced my father instructed my brother to pay with their credit card (being my fathers credit card but used by my brother for business). There was insufficient funds on the credit card, so I immediately produced my card so as not to cause any embarrassment and paid half and they paid half. At that time, being more concerned about the death of my mother, this incident didn't concern me much, however my father indicated at that time that he will retrieve this payment from the travel insurance and reimburse me.

Proceeding from there he did make a sincere attemt to retrieve the funds from the insurance but to no avail. Its been 2 years since the mayyit and I never considered this payment as being owed to me by mother or by her estate. Now that the estate is being finally wound up and all outstanding amounts settled, will it be correct for me to request the estate to settle this amount?

Taking an oath

Q: A girl said some words on the phone to her cousin (Irfan) in Ramadhan, sitting on prayer mat after salah. The words are "I never show my face to Khalid (cousin) and never try to meet him just let me talk to Khalid on phone call, if I did so, I will see my mother's dead body". Girl said that, its my oath or qasam. Now what she have to do if she wants to meet Khalid. Is there any kind of kaffara for it?

Designing a bible app

Q: I am a mobile application developer. I have been working on a bible mobile app for years. For a couple of days I am feeling that being a Muslim I should not have done this. Was it wrong? I will immediately stop doing it if this is not good but what should I do about my past, would taubah be enough?
