My great grandfather in his life time allotted a bigger share of his family inheritance to one of his grandsons compared to the rest and it is causing resentment among them. Is this halal according to sharia?
Note that this is family inheritance coming down generations and not created or bought by my great grandfather.
He had this right to gift any of his property to anyone he wanted and it doesn't matter that he himself inherited these properties and didn't acquire them through his own endeavors
