This is a topic that generates many questions and an area that attracts a lot of attack towards Islam, yet hardly discussed, not even on this forum. Muslims of all sects, including hadith rejecters, believe that verses of inheritance are very clear and are almost gathered in one verse, which makes it very straight-forward, thus easier to understand than other topics. I, too, shared this belief until I read Shahrour's (Towards new rules of jurisprudence related to women) a few years ago.
I will translate this part from the chapter on " Bequest and Inheritance", and eagerly hope that we discuss it and evaluate this new understanding. My replies will be based on the ideas of Prof. ShaHrour's.
Flaws in "Islamic" law regarding the bequest and the inheritance:
1. Priority is given to laws of inheritance over those of bequest.
2. Abrogation of vreses on bequest, especially the part of "...that he makes a bequest to parents and next of kins" 2:180 by a weak hadeeth: "No bequest to a heir".
3. No distinction is made between "share (naSeeb): نصيب " which relates to bequest, and "share (HaDh: حظ " which relates to inheritance.
4. No distinction is made between general interest, reflecte on inheritance verses, and family/specific interests, reflected by verses ofn bequest, ignoring that the general does not cover the specific.
5. Treating "if they were women more than two" as if it means "if they were two or more women) 4:11
6. Interpreting th word "walad/child:ولد " in verse 4:11 as "male child/boy" and as a reult, only a male child can keep all the inheritance within the family. This is contrary to the verse: يوصيكم الله في أولادكم للذكر مثل حظ الأنثيين God commands you regarding your children: to the male a portion equal to that of the two females, where males and females are both included under "walad:singular/awlaad:pl", and is also a contrary to the rule of the language where there are unisex words such as zawj (espouse), insaan (mankind), armel (widow/widower).
7 Inventing calculations that are not 100% of the inheritance (as a result of the flaws in 5 and 6 above), leading to giving those who should not inherit a share of the inheritance that was supposed to go to the heir (heiresses for that matter).
8. Preventing grand children to inherit their grand father if their father died befor the grandfather, although they are mentioned in verses of inheritance.
9.Giving relatives such as uncles part of the inheritance they are not entitled to.
