Inheritance is the practice of passing on property, titles, debts, rights, and obligations upon the death of an individual. The rules of inheritance differ between societies and have changed over time.
1. If the deceased left only one son and one daughter, and no wife, the daughter will inherit one third and the son wll inherit two thirds.
2. If the deceased left two sons and three daughters, and no wife, the wealth left must be divided in to seven equal parts, one part ( 1/7) for every daughter and two parts (2/7) for every son.
The tragedy of Lady Fatimah (SA) and her sufferings from Abu Bakr is mentioned in
hundreds of Sunni books and thousands of Shia books. I will mention
only the book of Bukhari being the most important book of Hadeeth among
our Sunni brothers. In the book of Bukhari, Hadeeth number 4240, it is
mentioned that Fatimah asked Abu Bakr to give her her right from what
the Holy Prophet (SAWA) left. Abu Bakr refused to give anything of
that to Fatimah (SA) so she became angry with Abu Bakr and boycotted
him and did not talk to him till she died. She remained alive after
her father for 6 months and she never spoke to Abu Bakr. This is in
the book of Bukhari itself.
It is important to know that Bukhari himself narrated a Hadeeth from
the Holy Prophet (SAWA) that Fatimah (SA) is part of me, anyone who
makes her angry makes me angry – this is in Bukhari, volume 4, page
210 in the Arabic edition.
The persons who have right in inheritance in Islam are in degrees; the first degree is for the parents of the deceased and the sons and daughters of the deceased. If any son or daughter are alive when the deceased passed away, no inheritance for grand sons or grand daughters.
In your question, the inheritance goes to the living sons and daughters, and no right of inheritance for the grandchildren. Grandchildren would have share in the inheritance if the deceased did not leave any living son or daughter.
Yes, it is allowed for any one to make a will in favor of any one whether a son or wife or friend or any one whom he wants. The will is obligatory in one third of the estate, but if it goes more than one third, then it will require the permission of the inheritors in the part which is more than the one third.
No, unless the grand father makes a will to give them whatever he wants to give them.
Inheritance goes to the direct children who are alive when the grandfather passed away and in the existence of direct children, no inheritance to grandchildren but with a will.
f the grandfather when he passed away had no living children but only grandchildren then all of them get the right is inheritance.
If the grandfather left only grandchildren with out any son or daughter, then all the grandchildren will inherit from their grandfather. But if the grandfather has living children, then his children will inherit him, not his grandchildren.
If the grandfather made a will in favour of his grandchildren, they will get a share according to the will which should not exceed on third of the whole estate, unless other inheritors permit.
If husband dies, his wife gets one eighth (1/8) from whatever he left if he left children, and if he had not leave any children, then she gets one forth of whatever he left.
Husband is allowed to make a will in favor of his wife , but the will is limited to one third of whatever he leave behind. More than one third will be the right of all the inheritors. If they agree to give her, then it s for them, but up to one third is obligatory.
The value must be based on the current value and not the cost price. If any one from the heirs wants to buy the share of others, he must pay them according to the current value of the property.
Islam respects and implements the will as far as it does not contradict the Islamic rules. The inheritance trust should not have any injustice on other inheritors, and it should not exceed one third of the whole amount left after deducting the debts and liabilities.
If the inheritance trust exceeds one third, then it will be in the hands of the inheritors to allow the extra amount or to just fix it to the one third.
There is no difference in this regard between any of the grandchildren. As long as a child lives his or her children or the children of other siblings would not inherit.
If you are sure that the whole amount of inheritance is unlawful then you are not allowed to utilize any amount of it, but give it to poor in charity through the Marja of Taqleed.
If you know that part of the amount is unlawful, then you are allowed to utilize the portion which is from allowed income.
The wife will gain her dowry(Mahr) from the property because it's a debt + one 8th of the property because the dead person had children.
Then the rest of the property will be divided between the children with the formula of: "The share of boys is twice the share of girls"
وَإِن كَانُوا إِخْوَةً رِّجَالًا وَنِسَاءً فَلِلذَّكَرِ مِثْلُ حَظِّ الْأُنثَيَيْنِ
But if there be [several] brothers and sisters, then for the male shall be the like of the share of two females. (4:176)
