Sahih Muslim
The Book Pertaining to the Excellent Qualities of the Holy Prophet (may Peace be upon them) and His Companions (Kitab Al-Fadail)
Book Number: 030 / Hadith Number: 5657
Anas b. Malik reported: I saw Allah's Messenger (may peace be upon him) during the time of the afternoon prayer and the people asking for water for performing ablution which they did not find. (A small quantity) of water was brought to Allah's Messenger (may peace be upon him) and he placed his hand in that vessel and com- manded people to perform ablution. I raw water spouting from his fingers and the people performing ablution until the last amongst them performed it.
