It was narrated that Anas said:
"Some of the Companions of the Prophet (ﷺ) were looking for (water for) Wudu'. The Messenger of Allah (ﷺ) said: 'Do any of you have water?' He put his hand in the water and said: 'Perform Wudu' in the Name of Allah.' I saw the water coming out from between his fingers until they had all performed Wudu'." Thabit said: "I said to Anas: 'How many did you see?' He said: 'About seventy.'"
