Sahih al-Bukhari Book 74, Hadith 35
Allah's Messenger (ﷺ) drank milk and then rinsed his mouth and said, "It contains fat."
Allah's Messenger (ﷺ) said, "The best object of charity is a she-camel which has (newly) given birth and gives plenty of milk, or a she-goat which gives plenty of milk; and is given to somebody to utilize its milk by milking one bowl in the morning and one in the evening."
I was raised to the Lote Tree and saw four rivers, two of which were coming out and two going in. Those which were coming out were the Nile and the Euphrates, and those which were going in were two rivers in paradise. Then I was given three bowls, one containing milk, and another containing honey, and a third containing wine. I took the bowl containing milk and drank it. It was said to me, "You and your followers will be on the right path (of Islam)."
