[Machine] Isaac narrated that Abdur-Razzaq narrated from Ma'mar who narrated from Az-Zuhri who narrated from Abu Salamah who said: Ibn Abbas reported that a man came and said, "A man died, leaving behind his daughter, sister, father, and mother. He said, 'The daughter should receive half and the sister should receive nothing.'" The man said, "But Umar ruled otherwise and gave half to the daughter and half to the sister." Ibn Abbas said, "Do you know better than Allah?" I did not understand the reasoning behind this until I met Ibn Tawus and mentioned the narration of Az-Zuhri to him. He said, "My father informed me that he heard Ibn Abbas saying that Allah Almighty said, 'If a man dies leaving no child but has a sister, then she shall have half of what he left.' (Quran 4:176)" Ibn Abbas said, "Therefore, you should give her half even if he had children."
