Commemoration

Imprisonment of Imam Musa al-Khadim (as)

Harun al-Rashid imprisoned Imam Musa al-Kazim due to several reasons: the Imam's high personality and recognition as the rightful Imam by Muslims, evoking Harun's envy and malice; his craving for power, fearing the Imam's superiority; inherited hatred toward Alawids; informers accusing the Imam of collecting money and seeking caliphate; the Imam's demonstrations of his closer relation to Prophet Muhammad; specifying vast borders for Fedek; and the Imam's firm, non-flattering attitude toward Harun.

Departure of Imam al-Hussain (as) from Makkah to Kufa

Imam Hussein departs Makkah against warnings from his uncle Ibn Abbas and brother Mohammad-e-Hanafiya, leaving a letter declaring his intent to revive the Ummah's adherence to Amr-bil-Marouf and the path of his grandfather and father Ali. His journey to Kufa includes 14 stops: meetings with supporters like Zohair, dissuasion attempts, news of Muslim's death reducing followers to 50, a sermon at Baiza on tyranny, and aiding Hurr's thirsty army. Bypassing Kufa, he reaches Karbala on 2nd Muharram 61 Hijri, foreseeing martyrdom.

Eid al-Adha

Eid al-Aḍḥā, celebrated on Dhu l-Hijja 10, commemorates Prophet Ibrahim's near-sacrifice of Isma'il, replaced by a ram from Jabra'il. Muslims perform sacrifices in Mina during Hajj as remembrance. Emphasis is on worship: vigil on the eve, ghusl, Eid Prayer, sacrifice, ziyarah of Imam al-Husayn, and al-Nudba Supplication. Fasting is forbidden, and it is an official holiday in Muslim countries with public ceremonies.The story details Ibrahim's submission, where the knife wouldn't cut, leading to God's acceptance and the ram's sacrifice. Imam Ali recommended vigils on this night.
