Hey ur crazy i think ur Moslem priests are misguiding you!
Shiva linga is not a physical Linga..its Atma linga ....the shape of the eternal Soul or ParBrahma....by saying this u have insulted Allah Himself...
Go and see what u have in Kabba which was obce called Makkeshwar Temple! Its a black stone now decorated/covered with steel...its a very ancient SHIV LINGA...one among the fourteen all over the world!
