"The Prophet asked me: "What is in your Idawah (water skin)?" I said: "Nabidh." He said: "Dates are wholesome and water is pure." He said: "So he performed Wudu with it."
Jami` at-Tirmidhi Book 1, Hadith 88
← Previous Hadith "Allah's Messenger vomited so he performed Wudu." So I met Thawban in a Masjid in Damascus, and I mentioned that to him. He said: 'He told the truth, I poured the water for his Wudu."

Jami` at-Tirmidhi Book 1, Hadith 87 Next Hadith → the Prophet drank milk. Then he called for water to rinse out his mouth. Then he said: "Indeed it has fat." There are narrations on this topic from Sahl bin Sa'd As-Sa'idi and Umm Salamah. Abu Eisa said: this Hadith is Hasan Sahih. Some of the people of knowledge held the view that one is to wash the mouth after drinking milk and this is recommended according us. Some others did not hold the view that one is to wash out the mouth after drinking milk.
