3May

Celebration

Birth Ali al-Akbar (as)

Ali al-Akbar, eldest son of Husayn ibn Ali (third Shia imam and grandson of Prophet Muhammad), was born to Layla from the Banu Thaqif tribe, with maternal ties to the Banu Umayya through her grandmother Maymuna. Praised by Caliph Mu'awiya for embodying traits of Banu Hashim, Umayya, and Thaqif, he strikingly resembled Muhammad in appearance and manners, earning the epithet Shabih-e Payghambar. His age at the Battle of Karbala (680 CE) is disputed (18-25 years), with 25 most likely, as he was older than survivor Ali Zayn al-Abidin (likely 23).

Celebration

Birth of Imam al-Mahdi (as)

On July 29, AD 869, Imam Mahdi was born amid divine light, testifying to God's oneness, prophets' prophethood, and ancestors' Imamate while bowing toward the qiblah. Angels descended to congratulate Imam Hasan, and the infant recited holy books of past prophets. Archangel Rizwan washed him, Imam Hasan transferred wilayah and recited adhan. Green birds (angels led by Gabriel) took the newborn to God's Throne, where He affirmed Mahdi's role as the last proof, promising justice through him.

Event

Beginning of the Major Occultation

The Major Occultation began in 328 A.H. after Ali bin Muhammad Samari's death, with deputyship passing to great jurists; the Imam communicated via letters and audiences to Shia scholars like Shaykh Mufeed. Hypocrites like Ahmad bin Hilal, Hasan Sharii, Husain bin Mansur al Hallaj, and Muhammad bin Ali Shalmaghani falsely claimed deputyship due to jealousy or greed, promoting deviations and facing curses or execution.

Death of Khadijah al-Kubra (as)
