Hundreds of shrines -- many that are centuries old -- dot Pakistan, where several million Muslims are believed to still follow Sufism.

Visiting shrines to pray and offer alms to the poor -- and cash to the custodians -- is very popular in Pakistan, where many believe it will help get their prayers answered.
