If a woman passes away and leaves behind her husband and both parents, the inheritance is distributed as follows: the husband receives half of the estate, the mother receives one-third in full, and the remaining portion goes to the father, which amounts to one-sixth. This distribution aligns with the verse of Allah سبحانه وتعالى Almighty: "But if he has no child and his parents inherit from him, then for his mother is one-third" (Surah An-Nisa 4:11). Allah سبحانه وتعالى granted the mother a complete one-third share when there are no children or siblings. Al-Fadl explains that this is evident because even those who disagree with this ruling do not assign the mother one-sixth in this scenario. Instead, they claim the mother receives one-third of what remains after the husband's share, which effectively equals one-sixth. They sought to adhere to the wording of the Quran but deviated from its intended ruling, which is misleading and contrary to Allah's سبحانه وتعالى Book. Similarly, in the inheritance scenario where a woman dies leaving behind her husband and both parents, the husband receives one-fourth, the mother receives one-third, and the remainder goes to the father. Allah سبحانه وتعالى explicitly mentioned in the Quran the shares for the husband and wife but did not specify a portion for the father, indicating that the father inherits what remains after the specified shares are distributed. This ensures that the father's inheritance comes from what is left after the fixed shares have been allocated.
