If we look at the Glorious Qur’an, we find that the details of the rules of the inheritance came in a comprehensive and complete form. On the other hand, the other rules of fasting, prayer, hajj, and zakat, these rules came in a summary form, but the details came from the narrations on the tongue of the Prophet (prayers and peace of Allah be upon him and his family). We can note this accuracy in detail, for example, in Surat al-Nisa, verse 11, the male has the same share as the share of two females, and if the women are more than two, then they have a third of what he left, and if she is one, she gets half.
In spite of that, we notice some stray arrows trying in vain to undermine these divine rulings, but these arrows are returned to their owners, as all scholars all over the world have recognized that the fairest system of inheritance is the system of the Glorious Qur’an.
This research is divided into three sections. The first section is the concept of inheritance, the reasons for its revelation and its verses. The second section is the inheritance of men. The third section is the inheritance of women and the inheritance of the mother. One of the sources that the researcher relied most on is the interpretation of Al-Kashef by Sheikh Muhammad Jawad Mughniyeh.
