Narrated Ibn 'Umar: "I had a dream in which I saw as if there was a piece of silk in my hand, and I would not gesture to any place in Paradise except that it would fly with me, (taking me) to it. So I told the dream to Hafsah, so she told it to the Prophet (ﷺ), so he said: 'Indeed, your brother is a righteous man,' or 'Indeed, 'Abdullah is a righteous man.'"
