Can someone help me get the idea that a widower gets more money than widow

[huruf]

I have answered, I think clearly, several times. You opened several threads with the same subject. Now I do not know what was in which.

I will repeat. As to children I quoted to you the aya where it says clearly

4.11
Allah instructs you as to your children to the male like the share of the two females. If thereare more than two women, to them two thirds of what left (the deceased),if only one daughter to her half.

As you see, the portions are determined as a function of the number of daughters If there are two daughters and one son, each of the three gets the same amount.
If there is one daughter she gets half and the sons the rest, if there are three daughters or more for them two thirds and for the sons the rest, that is, one third.

So in the case where there are three daughters or more, you distribute it yourself and see.

If there is a sex favoured, it is the women. On the whole this system of distribution favours that a sex which would be in a very noticeably minority would get proportionately more with some advantage for women.

Again, the case of three daughters They get two thirds of the whole. They cannot get less. If there is only one son and three daughters, the three daughters get two thirds, then the one son would get the other third. Proportionately he would get a bit more than each daughter. However if they are three daughters and two brothers, the three daughters would still get two thirds so one third would be left to disribute amongst two sons, so each brother would get less than each daughter.

And you can do any number of calculations on that base.

The amount for the females, the Qur'an determines first. Then what is left is distributed amongst the males.

If one daughter, she gets half, the males the rest.
If two daughters and one son, each get a third
If three or more daughters, the daughters get two thirds, the rest is distributed amongst the males.
