Who are the heirs of a deceased mother, what is the share of each heir from her estate, how are her properties divided, and what is the ruling on one of the sons saying that his mother forgave him her debt before her death?

Grandchildren, and the brothers and sisters of the deceased woman, do not inherit from the grandmother if her direct son is alive. If the deceased left no heirs except her husband and five sons, then the husband receives one-fourth due to the presence of lineal descendants, and the remaining portion is divided equally among the five sons. All gold and belongings left by the woman are considered part of the inheritance and must be divided among the heirs according to Islamic law. If an heir acknowledges a debt owed to the deceased, he is obligated to return it to the inheritance unless the other heirs waive it. If he claims that his mother absolved him of the debt before her death while she was not in her death illness, and the heirs confirm this, then he owes nothing. However, if the absolution occurred during her death illness, it is considered a bequest to an heir, which is impermissible unless the other heirs approve it. If he claims not to know the exact amount of the debt, the heirs should reconcile with him.
