Hadith no 191 and 192 are repeated. Read them here.
Allah’s Apostle came to visit me while I was sick and unconscious. He performed ablution and sprinkled the remaining water on me and I became conscious and said, “O Allah’s Apostle! To whom will my inheritance go as I have neither ascendants nor descendants?” Then the Divine verses regarding Fara’id (inheritance) were revealed.
This is why people fought over that remaining water. It was so effective!
