The Prophet's dreams of Umar: the palace in Paradise and the milk

Abu Hurayra (may God be pleased with him) relates that the Prophet ﷺ saw in a dream that he was in Paradise, and a woman was performing wudu beside a palace; he asked: for whom is this palace? They said: for Umar. The Prophet remembered Umar's jealousy and turned away, and Umar wept saying: do you envy me, O Messenger of God? ¹ Bukhari 3680. The like was told of a second dream: the Prophet saw himself drink milk until he saw the excess flowing from his fingernail, then he handed it to Umar; when asked its interpretation he said: knowledge ¹ Bukhari 3681.

In these two dreams are the merits of Umar ibn al-Khattab (may God be pleased with him): his greatness in Paradise such that the Prophet refrained from looking at his palace out of respect for his jealousy, and the honour of knowledge God poured upon his hand until it overflowed to the people ¹.

Among the dream reports in the Two Sahihs concerning the Companions; the Jinn & Devils Browser shows it in the dreams section ¹.
