well said 2 shrines of of hazrat hussain (one in egypt and the other one is iraq), 3 shrines of hazrat ali in iraq, mizar sharif (afghanistan) and one in bulkh, 2 shrines reported for hazrat fatima (refer asool e kafi ).
u have mentioned firuoon… hope u have seen pyramaid (tombs of firoun) they are much more magnificient than the shrines u r referring to… is this ur criteria ? think.
what about more than one lack prophets, do u know about their graves. except for prophet muhammad (PBUH) none of prophets’ grave are authentically known … what u say about it.
brother i havent tried to make ne comparison btw hazrat hussain and yazid. everybody has its own virtues and limitations. so dont make ne human being divine and lable the rest as devil.
