PROOFS AGAINST MATAM AND LAMENTING FROM SHIA SOURCES

We Muslims are aware of the prohibition and curse which befalls upon the one who laments or wails the wailing of Jahilliya, i.e shouting loudly, crying loudly, hitting and beating oneself, tearing the clothes, abusing and etc. These are not permitted in Islam. However, an off-shoot of Islam - the shia'a sect, on the contrary held anniversaries and  celebrations for Matams, and i shall quickly In sha Allah enlist some ahadeeth along with their tahkeeq from the shia'a sources itself to prove the impermissibiliy  of matam.
