Delivering debt to the deceased's heirs

A: It is obligatory that you repay the debt to your brother's inheritors. If the reality is exactly as what is mentioned in the question, your brother's inheritors are his wife, his mother, and his father. The brothers and sisters of the deceased are not entitled to receive any part of his inheritance because they are excluded by their father. The estate of your brother is to be divided into twelve shares. One quarter for the wife = three shares, one sixth for the mother = two shares, and all that remains should be given to the father = seven shares. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
