Anyone who has truly studied the life of Imam Hussain and Hassan (RA) will know it as a fact that he never wanted his followers to do all this nonsense or do Self harm also know as Matam.
Our bodies have a right upon us and it is a fact that on the day of judgement our bodies will speak and be a witness infront of Allah.
Our bodies are an amanah and gift from Allah. This is such massive abuse of soul and the body both.
Slapping someone on face is haraam. Cutting self, walking on coal and Self-Flagellation is downright haraam and a massive bi’dah and clear deviation from the religion of Prophet Muhammad (salallahu aleyhi wasallam).
SHAYTAN LOVES BI’DAH
“Innovation is more beloved to Iblees (Satan) than sin, since a sin may be repented from but innovation is not repented from.”
– Sufyan Ath Thawree (ra)
Bid’ah (innovation) means “a newly invented matter”.
The Shari’ah definition of bid’ah is: “A newly invented way [beliefs or action] in the religion, in imitation of the Shari’ah (prescribed Law), by which nearness to Allah is sought, [but] not being supported by any authentic proof – neither in its foundations, nor in the manner in which it is performed.”
The Messenger (sallallahu ‘alaihi wa-sallam) also warned against the People of Innovation, from befriending, supporting or taking from them (an act of bid’ah) saying: “Whoever innovates or accommodates an innovator then upon him is the curse of Allah, His Angels and the whole of mankind.”
Reported by Bukhari (12/41) and Muslim (9/140)
The Prophet (peace and blessings of Allaah be upon him) said: “He is not one of us who strikes his cheeks, rends his garment, or cries with the cry of the Jaahiliyyah.”
Al-‘Irbaad ibn Sariyah (radi Allahu ‘anhu), reports that the Prophet (sallallahu ‘alaihi wa-sallam) said, “…. I have left you upon clear guidance. Its night is like its day. No one deviates from it after me except that he is destroyed.”
Reported by Ahmad, Ibn Maajah (no. 43) and al-Hakim.
Al-Marwazee (radi Allahu ‘anhu) reports in as-Sunnah (no. 95) that ‘Umar ibn ‘Abd Allah-‘Azeez (radi Allahu ‘anhu) said, “There is no excuse for anyone, after the Sunnah, to be misguided upon error which he thought was guidance.”
