 For those who ask, why do Shi'a do Tattbeer and Zinjil? Some Shi'a practice bloodletting on the days of mourning for Ahl al-Baita, which involves the striking of the head with a sword known as Tattbeer, or striking the back with blades known as Zinjil. This is a controversial topic that divides the believers with some being in favor of it and others being completely against it. Amongst the evidence given for bloodletting include a narration concerning Lady Zainab al-Salam, when she saw the head of her brother, mounted upon a spear. She hit her forehead on the front of a pole until we saw blood coming out from under her veil. Furthermore, Imam al-Mahdi al-Salam is reported to have said concerning his grandfather Imam Hussain al-Salam, I will therefore lament for you mourning and evening and I will weep blood instead of tears out of my anguish for you and my sorrow for all that befell you. Different Maraji'a have come to different conclusions as to whether the faithful should practice Tattbeer and Zinjil. Therefore, a person should refer to their Maraji'a. For example, his eminence, the Grand Ayatollah Sayed Saadiq Shirazi has stated, Bloodletting is halal and recommended as long as it does not lead to the death of a human being, the stopping of a body limb from working or the prevention of reproducing children. Wherever Fetua a person follows or whatever form of Azadari a person performs, the main thing all Muslims should remember regardless of whether they agree or disagree with bloodletting is the importance of conducting ourselves in an honorable and dignified manner, which represents the school of Ahlul Bayt al-Salam in the best of ways. May Allah SWT make all of us adornments of Ahlul Bayt al-Salam and help us to invite others to the sublime path. Thank you.
