Questions related to Qadha and Kaffaara for fasting

Q: Are the rules same for intentionally breaking a fast in Ramdhan, and not keeping a fast at all for no valid reason? Under what circumstances do we have to do kaffara and under what circumstances do we have to do just qadha? Does breaking a fast just because you were hungry or you felt you don't want to fast anymore need qadha and kaffara or just qadha? Does not fasting at all need kaffara as well as qadha or just qadha?

Suspending talaaq upon disobediance

Q: If somebody told his wife "If you don't listen to me or will not listen to me then talaaq" two times in away when he said to her first time she couldn't hear him because she is deaf and didn't wear hearing aids but she did hear him when he repeat the words again. Just in case if she didn't hear him, will one or two talaaqs take place? My questions is how can she act upon the warning if she couldn't hear when he said it first time?

Inheritance Question

Q: My question is regarding the claim that the inheritance proportions as prescribed Quran in surah an-Nisa don't add up in some case. An example is this:

A second example is, that when a man leaves only his other, his wife and two sisters, then they receive 1/3 [mother, 4:11], 1/4 [wife, 4:12] and 2/3 [the two sisters, 4:176], which again adds up to 15/12 of the available property. 

What is the fact of the matter? and are principals such as al-awl(?) applied? If so, why are they applied if they aren't mentioned in the Quran?

Breaking ties with a person who has bad habits

Q: I would like to know if breaking ties with a family member is allowed, because my husband's sister does all the wrong stuff like going clubbing she and indulges in adultery, smoking, consuming alcohol and drugs. The only reason that I have to keep contact with her is because she had taken a loan from me and still has not returned it, but as soon as she pays me back I would like to break every relation with her, because I feel that she is a bad influence and I also have 2 daughters growing up so I would like to know if my decsion is correct?

Solution for those in despair and helplessness

Q: Please pray for me and give me guidance. My soul is so lost and broken. I am a sinful Muslim and have committed many sins against Allah. And now I realise the errors of my ways. I am in a very bad place and don't know how to gain my self respect back. I am in love with a man that does not love me, we are not married but were at one point intimate friends and hoped to be married. But things changed and he stopped loving me. However since then we have just been friends. Me being in the hope that he would realise that I love him much and he would marry me. However all this man has done is to take advantage of my feelings play with my emotions and leave me feeling like a worthless human taking advantage of my kindness. I know I probably deserve what I am getting now. But I am so sad and in despair. I need some help and support and don't know what to do. My situation is so bad I have been humiliated and shamed by him through the way he speaks to me and the things he does and how he constantly toys with my emotions. I need help please advise me on how I can get it together and loose the love of this man from my heart for I have tried for 10 years or more. He will not leave me alone always calling me and manipulating me and I am weak and always fall for his traps and he uses my friendship to make fun of me for amusement. Yet I can't fight this or see this for what it is. Please give me a prayer or wazifa. I know my request is shameful but I have no one to turn to.
