Takhrij Hadith 742: "In a dream, I was…"

In a dream, I was brought a large bowl filled with milk. I drank from it until I was completely satisfied, and I saw it flowing through my veins. Then there was some left over, and 'Umar ibn al-Khattab (may Allah be pleased with him) took it and drank it." He ﷺ said: "Interpret it." They replied: "This is the knowledge that Allah, the Mighty and Majestic, has given you. When you were filled with it, there remained some, and 'Umar ibn al-Khattab took it." He ﷺ said: "You have interpreted it correctly."
