Commemoration

Martyrdom of Fatima al-Zahra (as)

After the Prophet's death, a group of up to 4000 men, led by Umar ibn Khattab, demanded Ali ibn Abi-Talib's allegiance to Abu Bakr at Fatima tuz Zahra's door. Ali, preparing the Qur'an, refused. They threatened to burn the house, set fire to the door, kicked it in, injuring Fatima—breaking her rib and causing miscarriage of Al-Muhassin. On her deathbed, Fatima requested a secret night burial attended by few loyal companions like Ali, al-Hassan, al-Husayn, Ammar bin Yasir, and Salman al-Muhammadi. Her grave's location remains unknown. Ali, who lifted Khaybar's gates effortlessly, wept unable to lift her body.

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.

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’.
