In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
It appears that you are confusing a Will with the laws of inheritance.
It is true that the laws of inheritance where the heirs inherit from the deceased are clearly stated in the Quran and Ahadith.
Allah Subhana wa Ta’ala explains in the Quran who is entitled to the inheritance and in what proportion. Allah says:
For the male the share is twice that of the female. If there are only females together they will get a total of two-thirds of the estate etc.[1]
This entire ruku is dedicated to the division of shares for different heirs.
However, we are living in non-Muslim countries which have their own laws of inheritance. For example if one passes away without making a will that his estate should be divided according to Shariah Laws of inheritance, then the Intestate laws of inheritance of that country will be applied. This is against Shariah. Therefore, it is imperative that one should make a will stating that after his demise his estate is to be divided according to the Shariah law of inheritance.
In a will one may also record the following:
- Debtors
- Creditors
- Trusts
- Fidiya and Kaffara for missed Salat and fasts
- Record any other matter of importance.
And Allah Ta’āla Knows Best
