Inheritance Question

Q: We are four brothers and three sisters of whom one sister is unmarried. One of our brothers was working abroad. He died 2 years ago and left behind one widow and a son of about eight years. Our parents have already died. We have distributed the rest of the property of our deceased brother. But now we have received the salary arrears and other benefits of our deceased brother in cash. I want to ask that how this cash amount will be distributed. The rest of my brothers are of the opinion that as they sponsored all the expenses of sending our brother abroad so they are entitled to receive all the cash.

Receiving the rewards for fasting on virtuous days

Q: I made a vow that if I commit a certain sin I will fast for 3 consecutive days. Unfortunately I fell in to this sin many times after so I have 27 fasts to keep. If I fast with the intention of these fasts on days that are virtuous to fast like the first 9 days of Zul HIjjah, 13 14 15 of each month will I receive the thawaab that comes with normally fasting on these days or will only my vow be carried out?
