Sayyiduna Uqbah bin Amir al-Juhani (may Allah be pleased with him) said that the Messenger of Allah (peace and blessings be upon him) said: "When I was taken up to the heaven on the Mi'raj, I entered the Garden of Eden, and an apple came into my hand. When I placed it in my hand, it split open and from it emerged a houri with large eyes, well-pleasing, whose eyelashes were like the front feathers of eagles' wings. I asked her: 'To whom do you belong?' She said: 'I am for the caliph who comes after you.'"
