It is narrated from Sha'bi (may Allah have mercy on him) that Sayyiduna Umar, Sayyiduna Ali, Sayyiduna Zaid, and I think Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with them all) all said: The right of inheritance (wala') is for the closest, and by "closest" they meant the one who is nearest to the father and mother.
