Cutting hair and nails during haidh

Q: Please advise regarding the following:

1. Is it permissible to cut nails and hair during menstrual period? Elders say to keep it safe until haidh/nifas period is over and to wash it off after that and to bury it. 

2. Is there any specific dua in Qur'an or hadees to change the husband into obedient slave of Allah (because he is not convinced of Allah's wrath if he commits zina after marriage. He refuses to stop contacts with a Christian lady over social media saying that theirs was and will be pure frienship. But I knew few months back that they committed zina several times and continuing contacts even after she married another guy). I wish Allah will change him one day eventhough I know very well that he is very much addicted to her. It was his main hobby to chat with strange girls and became close to them. He isnt stopping it after our marriage. He isnt serious about life after death. I dont want him to die as a person who committed zina. I love him sincerely eventhough I wished and prayed before nikaah that the person who marry me will be a religious guy who is concious of deen. My family will consider me as a burden if I become a divorcee, even if I struggled alot and have valid reasons to seek divorce.

Repenting for any sin

Q: Can we as Muslims repent for even the most heinous sins? I mean anything!!! Any serious sin can be forgiven through true repentance? The word any is important here, it covers any/all/every sin a human being can commit!!! Or is there any limitations to Allah's mercy!

Distributing inheritance

Q: I have a moral dilemma which I need some help and guidance with. My husband passed away a few months ago and we are in the process of distributing the inheritance within the heirs. I have a son and a daughter and his both parents are alive. There are two sums of money. One was given by the office to me and I want to distribute it among ourselves according to shariah. This was totally my husbands money. The other is our savings in which we both contributed but were in his name. My contribution included the money I got from my father as well as the savings I did when I was working. My question is do I deduct my portion from our savings before distributing it according to shariah? Or since it was no longer in my name I cannot claim it and all of the savings will be divided. One problem is that the matter is being settled by court in the form of succession certificate where it is expected that the court will keep the children's inheritance for safekeeping until they are 18. That means I will have access to only the amount that the court will give to me i.e. 1/8th. Kindly advise what should I do.
