Tassoua – July 5, 2025

Tassoua is celebrated on the ninth day of Muharram, the first month in the Islamic calendar, and this year, that falls on July 5. It is a forbidden month for Muslims in the history of Islam because of the greatest tragedy and oppression of the Prophet’s family that occurred.

Several events occurred on this day. Its popularity among Muslims is derived from Ashura because ‘Karbala’ took place on the ninth and tenth day of the month of Muharram al-Haram.

History of Tassoua

Muharram is the most significant month for Muslims. Muslims around the globe recognize it as the advent of the Islamic New Year and regard it as an important festival. It’s one of the four sacred months of the year for Muslims. Muharram is the first month of the Islamic calendar and comes next to Ramadan in terms of significance. Muharram means ‘forbidden,’ and because it is holy, many Muslims use it as a period of prayer and reflection.

Many events take place during Muharram. One of them is Tassoua, which spells as ‘Tasua’ or ‘Tasu’a.’ It holds on the ninth day of Muharram, which is the eve of the martyrdom of Imam Husayn, the third Shia Imam. Husayn is a prominent figure in Islam because he was a member of the Ahl al-Bayt (the household of Muhammad). He is the grandson of the Prophet Muhammad through his daughter Fāṭimah and son-in-law ʿAlī (the first imam of the Shiʿah and the fourth of the Sunni Rashidun caliphs). He was also a member of Ahl al-Kisa, a Shia Imam, and one of The Fourteen Infallibles of Shia Twelvers. The Sunni and Shia recognize him as the ‘Martyr Of Martyrs.’

Tassoua precedes Ashura, on which Imam Husayn and 72 of his loyal companions died in the Battle of Karbala in Iraq over 1,300 years ago. They remember the massacre on Ashura day, and some choose to fast. Large mourning ceremonies are held at the Holy Shrine of Imam Reza in Mashhad and the Grand Bazaar of Tehran. Tassoua is also the traditional and religious ritual date of the 40 Minbar when women cover their faces and repeat zikrs (prayers) for God and light candles in memory of the martyrs of Karbala.
