You finally assured that you could not prove anything when you answered No
Your speech and your leaders are the same and have not changed ! You are arrogant and haughty .. I had explained this in my subject:
Allah stated some general bases,.. and did not say : in this very special case: give this one half and this one two thirds.. etc.
He rather put general shares that match with most of the cases as it is the case with the Holy Quran, and He left the rest for endeavoring starting from the same basis even it will be wrong if He selected a particular case and put along with it its own proportion and said this is for that but Allah the Almighty mentioned and clarified main cases.. the evidence for this comes in two forms:

-The scrutiny evidence : this condition is in Quran concerned issues that mentions the important rules and the apparent clarifying lines that enlightened by
-The method of Quran’s mentioning those cases from the side of linguistic expression , this needs detailed long explanation, He did not say: if two sisters, a wife and a mother with a son gathered give this one half and give that one eighth and to these two give two thirds!

And it is known that the rules are attributive sentences not predicative, this is the speech of all the experts.. and it is clear you are confused between them
And the judgment: give this one that and this one that and so one.. according to this and that condition.. If a new found case was not mentioned specifically and appears to be problematic this does not mean that it is wrong.. but it is understood that it needs solution because it was not mentioned, and its solution depends on the ingenuity of experts who knows most as Allah the Almighty speaking in Quran Himself mentions this.. The wrong is mentioning this case of gathering in a group and decide the shares as this and that then a mistake occurs during accounting, and concerning this we defy all of you mindless atheists.. Even when seems to be contradiction in appearance it can not be regarded as wrong logically only when the sum is impossible:
If the teacher said to his students: no one goes out from the room.. then he stood up and went outside, why it is true if someone says he is wrong! Because the speech is understood within its context and sphere
And for the sake of atheists, and those who are like them from the Islam enemies, to get involved in Quran issues with intentions to stub, doubt, disproof, hatred and intention to destroy , there is no wonder to say this is not correct
