Narrated `Abdullah bin `Umar: I heard Allah's Apostle saying, While I was sleeping, I saw a bowl full of milk was brought to me and I drank of it (to my fill) till I noticed its wetness flowing (in my body). Then I gave the remaining of it to `Umar. They asked, O Allah's Apostle! What have you interpreted (about the dream)? He said, (It is Religious) knowledge. (See Hadith No. 134)
