Is it permissible to give the collected debt amount to the questioner's mother, and how are the shares of inheritance distributed among the wife, sons, and daughters?

All assets left by your father—debts and money—are to be distributed among the heirs you mentioned, unless there are other heirs. The wife receives one-eighth, and the remainder is distributed among the males and females, with the male receiving the share of two females. The amount owed to your father by his cousin is considered part of the inheritance, and it is not permissible to give it to your mother unless it is equal to her share, which is one-eighth. Inheritance matters are complex and delicate and cannot be settled by a mere fatwa (definition); rather, they must be referred to Sharia (definition) courts for verification and to ascertain any other heirs, wills, debts, or rights that take precedence over the heirs' claim to the assets.
