"I entered upon the Prophet with a son of mine who was not yet eating food. He urinated on him, so he called for water which he sprinkled over it."
Jami` at-Tirmidhi Book 1, Hadith 71
← Previous Hadith "The Prophet passed by two graves. He said: 'These two are being punished. And they are not being punished for something major. As for this one, he would not protect himself from his urine. As for this one, he used to spread Namimah (slander).'"

Jami` at-Tirmidhi Book 1, Hadith 70 Next Hadith → "Some people from Urainah arrived in Al-Madinah, and they were uncomfortable (and ill from the climate). So Allah's Messenger sent them some camels from charity. He told them: "Drink from their milk and urine." So they killed the camel driver that Allah's Messenger sent, and they violently drove off the camels, and apostatized from Islam. So the Prophet came to them, he cut off their hands and feet on opposite side, and branded their eyes, and threw them in Al-Harrah." Anas said, "So I saw one of them working over the ground with his mouth, until they died."
