question #2 Sahih al-Bukhari 3572, Book 61, Hadith 81 : How did the companions of the Prophet benefit from the miracle of water at Az-Zawra?

A bowl of water was brought to the Prophet (ﷺ) while he was at Az-Zawra. He placed his hand in it and
the water started flowing among his fingers. All the people performed ablution (with that water).
Qatada asked Anas, “How many people were you?” Anas replied, “Three hundred or nearly three hundred.”
