To lecture on or discuss the Shahaadat of Hadhrat Imaam Hussayn (Radhiallaahu Ánhu) is Haraam even if the stories are true. (Fataawa Rashidiyya part 3 pg. 113)
The incident of the martyrdom of Hadhrat Hussayn (Radhiallaahu Ánhu) who sacrificed his life for the sake of Truth, is surely very important. But the method adopted, like beating the chest, tearing the garment, pulling the hair, slapping the face, shouting slogans of 'Yaa Hussayn, Yaa Hussayn' and taking out processions to parade in the streets, is what Hadhrat Moulana has stopped and said is Haraam.'
The reason for stopping this is that Rasulullah (Sallallaahu Álayhi Wasallam) has forbidden the slapping of faces and the tearing of garments.
Therefore to lecture on or discuss the Shahaadat of Hadhrat Hussayn in the abovementioned fashion, with that type of pomp and show, is forbidden in the light of the Hadith. (Fataawa Rashidiyya pg. 104/105)
