Sahih al-Bukhari Companions of the Prophet Hamza's father Sahih Allah’s Messenger (ﷺ) said, “While I was sleeping, I saw myself drinking (i.e. milk), and I was so contented that I saw the milk flowing through my nails. Then I gave (the milk) to `Umar.” They (i.e. the companions of the Prophet) asked, “What do you interpret it?” He said, “Knowledge.” https://parallelquran.com/hadith/sahih-al-bukhari-3523/
