MUSLIMS BRING HOME REVERED ZAMZAM WATER AFTER ANNUAL PILGRIMAGE
It makes perfect sense to carry water to the desert.
But why would anyone take the trouble to bring some back?
If it is Zamzam water, the answer is 1,400 years old: Muslims returning from the hajj, the annual pilgrimage to Mecca, value it as a liquid memento from the holy city.
Once home, they drink it for its perceived curative powers and give small amounts -- along with dates -- to friends and relatives as a means of celebrating the completion of their journey.
They may even set aside some for their death, when it can be used as a final ablution and to wash the burial shroud.
