Dr. Monzer Kahf, scholar in Islamic economics & financial expert, said,
When a deceased woman had a property in her name but did not leave any of her parents, and there is no evidence to indicate that the property was intended as a gift to anyone, this property may be shared to the heirs – “for the male, what is equal to the share of two females.” (An-Nisaa, 4:11). This is in accordance to the Islamic law of inheritance.
However, if we have anyone among the heirs that has spent a lot in taking care of the property and most likely is still willing to sacrifice for the other siblings; it is clear that recognizing such good action with gratitude and thankfulness is an act of goodness that our Shari’ah always recommends.
We are told by our dear Prophet that “He who does not thank people [for their good deeds], does not thank God too.”
To sum up, it would be appreciated if some shares of the property are forsaken to the person spending on the property in recognition of his long life good deed.
May Allah guide all to what pleases Him!
