Celebration

Birth of Imam al-Askari (as)

Imam Hasan al-Askari, the Eleventh Imam, was born in 232 Hijri in Madina and died in 260 Hijri in Samarra at age 28, after a 6-year Imamate under house arrest. Titled Askari for living in a garrison town, he taught Quran, wrote a Tafseer, and performed miracles like exposing a priest's rain trick and praying for rain. He married Nargis Khatoon, a Rum princess who converted via dreams, mother to his son Muhammad. Despite sufferings, he educated students and converted atheists. Poisoned by Caliph al-Mu’tamid, his 5-year-old son led his funeral prayer before disappearing. Buried with his father in Samarra.

Commemoration

Death of Fatima al-Masuma (as)

Lady Fatima Masuma (A), daughter of Imam Musa al-Kazim (A) and Najmah Khatun, was born on 1st Dhul Qa`dah 173 A.H. in Medina and died in Qum in 201 A.H. at age 28. Imams foretold her birth and burial in Qum over 45 years prior, promising paradise for her visitors and intercession for Shia. Known as Masuma and Karimat Ahl al-Bayt, she remained unmarried due to lack of suitable spouses amid persecution. A knowledgeable narrator of traditions, she was highly influenced by her father and brother, Imam Ali al-Rida (A).

Event

Uprising of al-Mukhtar al-Thaqafi to Avenge Imam al-Hussain (as)

The chapter examines Shi’ism's origins in political caliphal struggles, involving oligarchic timocracy and marginalized resistance, intertwined with religion unlike Western church-state separation. It details early divisions after Imams ‘Ali, Hasan, and Husayn, focusing on Mukhtar al-Thaqafi's 685-686 Kufah insurrection as enlightened messianic activist, avenging Husayn's death on behalf of Muhammad Ibn al-Hanafiyyah as Mahdi. Shi’ism is a metaphysical restoration of Prophethood through Imams' wilayah, not mere politics or founded by figures like Ibn Saba’.

25Apr

Celebration

Birth of Zainab (as)

Lady Zainab (as) was the third child of Lady Fatima az-Zahra (sa), born in 5 A.H. after Imam Husayn (as), refuting claims she followed a miscarriage of Mohsin, which historians like Bint Ash-Shati use to downplay the attack on Fatima's house. Named "Zainab" by the Prophet (S), meaning "embellishment of her father," or via Gabriel. Her life involved noble traits amid tragedies: deaths of grandfather and mother, father's confinement, his martyrdom, battles, Hasan's poisoning, Karbala massacre, captivity to Syria, return to Medina, and exile to Egypt, where her tomb is visited (though most believe it's in Syria).

30Apr

Event

Battle of the Camel

The Battle of Basra, or Battle of the Camel, marked the Second Civil War in Islam after Uthman's assassination and Ali's accession as caliph. Ayesha, Talha, and Zubayr, using vengeance for Uthman as pretext for their ambitions, raised a 3000-strong army in Mecca, captured Basra, killed 600 Muslims, and seized the treasury. Ali, after failed peace efforts and mustering 700 volunteers plus Kufan reinforcements, confronted them. Negotiations failed; Zubayr deserted and was killed, Talha died in battle, and Ayesha's camel became the focal point until slain, leading to rebel defeat. Ali showed mercy, pardoned leaders including Ayesha, and reunited the umma.
