What is the ruling of the Sharia regarding the distribution of the inheritance of a deceased person from 1990, who left behind a wife, four daughters, a paternal cousin, and a single house, where the house was divided after the wife's death in 1995 according to government law and not Islamic legislation among the four daughters?

If the deceased's paternal cousin is an heir (a full paternal cousin or a paternal cousin through the father's side), he has a share in the house. Similarly, the deceased wife's share is divided among her legal heirs. If the inheritance was distributed in a manner that contradicts Islamic law without reconciliation or mutual consent among the heirs, that distribution is not valid. The heirs must resort to Islamic law, as Allah Almighty says: ﴿But no, by your Lord, they will not believe until they make you, [O Muhammad], judge concerning that over which they dispute among themselves and then find within themselves no discomfort from what you have judged and submit in [full] submission.﴾ [An-Nisa': 65]. Allah Almighty Himself has clarified the shares of the heirs, and these are His boundaries. He has threatened those who transgress them with Hellfire and a painful torment, as Allah Almighty says: ﴿And whoever disobeys Allah and His Messenger and transgresses His limits - He will put him into Fire to abide eternally therein, and he will have a humiliating punishment.﴾ [An-Nisa': 14]. We advise the heirs to fear Allah and to re-divide the house according to the lawful Islamic division.
