Al- `Abbas b. `Abd al-Muttalib asserted that he was sitting in al Batha' [*] with a company among whom God's messenger was sitting when a cloud passed. They looked at it and God's messenger asked, "What do you call this?" and received the reply "Clouds (sahab)." He said, "And rain-clouds (muzn)," to which they agreed. He said, "And clouds (`aman)," to which they agreed. He asked, "Do you know the distance between heaven and earth?" and when they replied that they did not, he said, "The distance between them is seventy-one, seventy-two, or seventy-three years, the heaven which is above it is at a similar distance (going on till he counted seven heavens). Above the seventh heaven there is a sea the distance between whose surface and bottom is like that between one heaven and the next. Above that there are eight mountain goats the distance between whose hoofs and haunches is like that between one heaven and the next. On their backs is the Throne the extent of which from top to bottom is like the distance between one heaven and the next. Then God is above that." *A stony valley at Mecca. Tirmidhi and Abu Dawud transmitted it.
