زمزم
According to one legend, one of Uqba's soldiers stumbled across a golden goblet buried in the sands. It was recognized as one that had disappeared from Mecca some years before, and when it was dug out of the sand a spring appeared, with waters said to come from the same source as those of the sacred Zamzam Well in Mecca. This story led to Kairouan becoming a place of pilgrimage and then a holy city ("the Mecca of the Maghreb") and the most important city in North Africa.
