Re: How popular is Jhulelal worship in Pakistan
Muslims don't "worship" anything or anyone besides the One God. Allah in arabic.
Some ignorant masses do ask of the saints for help (in a form of duaa through the saints to Allah), or make a vow that if they get so and so, they'll come and offer the poor food, or offer a new covering for the grave, etc.
But worship is a rather strong way to describe it. No one worships the saint, and yes the saint is quite popular. One of many in Pakistan. City of Multan is known as the City of Saints because it has so many shrines.
