Musnad Ahmad 27:47

Isma'il narrated to us, Ayyub narrated to us, from Nafi', who said: Ibn Umar said: I saw in a dream as if there were a piece of silk in my hand, and I would not point with it toward any place in Paradise except that it would fly me to it. Hafsa narrated it to the Prophet, peace and blessings of Allah be upon him, and he said: "Indeed, your brother is a righteous man," or: "Indeed, Abdullah is a righteous man."
