ibn Mas'ud · The Book of Purification

It was narrated from 'Abdullah bin Mas'ud, that the Messenger of Allah (ﷺ) forbade cleaning oneself with bones or dung.

"The Prophet (ﷺ) wanted to defecate, and he told me to bring him three stones. I found two stones and looked for a third, but I could not find any, so I picked up a piece of dung and brought them to the Prophet (ﷺ). He took the two stones and three away the dung and said: "This is Riks." Abu 'Abdur-Rahman (An-Nasai') said: Riks is the food of the jinn.

"We were with the Prophet (ﷺ) 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 a means of purification and a blessing from Allah, may He be glorified.'" (One of the narrators) Al-A'mash said: "Salim bin Abi Al-Ja'd told me: I said to Jabir: "How many were you that day?' He said: "One thousand five hundred."
