The Martyrdom of Imam Hasan al-Askari is observed in Iran on the 8th day of the month of Rabi al-awwal, commemorating the 11th Imam of Shia Islam, who was born in 846. This observance marks the death of Imam al-Askari, who was poisoned at the age of 27 or 28 on the orders of the caliph al-Mu’tamid. His life was characterized by house arrest in Samarra, where he was prevented from connecting with Shia Muslims to suppress the faith. During this time, he focused on studying the Quran, Sharia, and various languages, which are believed to be part of the divine knowledge bestowed upon the Twelve Imams. The event highlights the significance of Imam al-Askari as one of the rightful successors to the Islamic prophet Muhammad and is part of the broader traditions and observances associated with Shia Islam in Iran.
