Unlike Hindu Law, estate of a deceased Mahomedan, if he has died intestate, devolves on his heirs at the moment of his death. Under the Mahomedan Law, birth right is not recognised
As per Sec.51 of Mulla Law about Inheritance, there is no distinction in the Mahomedan Law of inheritance between movable or immovable properties or between ancestral and self-acquired property.
In Muslim Law. three Classes of Heirs are recognized.
They are Sharers : Who are entitled to a prescribed share of the inheritance.
Residuaries : Who take no prescribed share, but succeed to the ―residue‖ after the claims of the sharers are satisfied.
Distant Kindred :- Those relations by blood who are neither sharers nor Residuaries.
Sharers: The Sharers are 12 in number and are as follows:
(1) Husband
, (2) Wife,
(3) Daughter,
(4) Daughter of a son (or son's son or son's son and so on),
(5) Father,
(6) Paternal Grandfather,
(7) Mother,
(8) Grandmother on the male line,
(9) Full sister
(10) Consanguine sister
(11) Uterine sister, and
(12) Uterine brother.
The per capita distribution method is majorly used in the Sunni law. According to this method, the estate left over by the ancestors gets equally distributed among the heirs. Therefore, the share of each person depends on the number of heirs.
Under Muslim law, the nearer heir totally excludes a remoter heir from inheritance. That is to say, if there are two heirs who claim inheritance from a common ancestor, the heir who is nearer (in degree) to the deceased, would exclude the heir who is remoter
Now you can decide who will get what under the Muslim personal law as per your question.
