Usurping the share of a child's inheritance
Q: My mother died when I was 8-9 months old and my father married another woman and had 2 more sons. But before that, my mother's property was all sold or distributed among many but me. I wasn't given a single portion of the property. And they even kept all this a secret from me till now, I wasn't even told that my real mother had died.
My question is that is this according to Islam, are they right or justified? And Is the selling and distributing of my real mother's property to others without her will (as she died suddenly) right/justified?
