I've been hearing that my siblings' sons have rights over my property after my death, even though I have two daughters, both major (no sons) and my wife. Is it true that male children of my brothers' will have a (or can ) claim rights over my property, in case of an absence of a will from me before my death ??? The propety in question is solely earned by me (not an ancestral property). Please clarify the legal details as per the shariat law. Thank You
