Sayyiduna Zaid bin Thabit (may Allah be pleased with him) was asked about the inheritance of a deceased woman’s husband and her full sister. So he gave half to the husband and half to the sister. And when he was spoken to about this, he said: Our leader, the Messenger of Allah (peace and blessings be upon him), made this very decision.
