What is the share of each heir from the estate of the deceased who left behind a husband, a mother, and a son?

If the heirs are limited to those mentioned, the husband gets one-fourth due to the presence of a lineal descendant heir, and the mother gets one-sixth due to the presence of a lineal descendant heir. The remainder goes to the son. Thus, the estate is divided into 12 shares: the husband gets 3 shares, the mother gets 2 shares, and the son gets 7 shares.

We emphasize that matters of inheritance are complex and intricate, and a mere fatwa is not sufficient. Rather, the matter must be referred to the Sharia courts for investigation, as there might be another heir, wills, debts, or other rights that take precedence over theirs.
