Then, when the heretics gained power, they ordered shrines to be built and mosques to be left unused, arguing that Friday and congregational prayers could only be performed behind the infallible imam. They transmitted lies concerning the lighting and veneration of shrines and supplication beside them, the like of which I have not encountered among the fabrications of the People of the Book that I have examined.
