Musannaf Ibn Abi Shayba 33:343

Abu al-Ahwas narrated to us, from Abu Ishaq, from Abu Ubaydah, who said: Abdullah said: "It is written in the Torah: 'Indeed, Allah has prepared for those whose hearts turn away from their beds what no eye has seen, no ear has heard, and has not crossed the heart of any human being, and which no angel or messenger knows.'" He said: "And we recite it: 'And no soul knows what has been hidden for them of comfort for eyes.'"
