Sunan An-Nasai, Chapter: The Book of Purification

"We were with the Prophet (saw) and they could not find any water. A vessel was brought to him and he put his hand in it, and I saw water springing from between his fingers. He said: 'Come to ameans of purification and a blessing from Allah, may He be glorified.'" (One of the narrators) Al-Amash said: "Salim bin Abi Al-Jad told me: I said to Jabir: "How many were you that day?' He said: "One thousand five hundred." (Sahih)
