After you have gone round the K'ba 7 times, the next thing
to do is to run between 2 mountains, again 7 times. This
is again representing a great event that happened long ago.
What you do, was done in search of water, and it was found
after the seventh time of passing between the two mountains.
This is the spring that you do to at the end, where you can
wash yourself, drink from it or do as you please.
