Sahih Bukhari

Narrated By Ibn 'Umar : I saw in a dream a piece of silken cloth in my hand, and in whatever direction in Paradise I waved it, it flew, carrying me there. I narrated this (dream) to (my sister) Hafsa and she told it to the Prophet who said, (to Hafsa), "Indeed, your brother is a righteous man," or, "Indeed, 'Abdullah is a righteous man."
