I heard Messenger of Allah ﷺ saying, "While I was sleeping, I was given a bowl full of milk (in a dream), and I drank of it to my fill until I noticed its wetness coming out of my nails, and then I gave the rest of it to ʿUmar." They (the people) asked, "What have you interpreted (about the dream)? O Allah's Apostle?" He said, "(It is Religious) knowledge." (Using translation from Bukhārī 7006)
