Husayn ibn Ali

Husayn ibn Ali, second son of Ali and Fatima and grandson of the Prophet Muhammad, was born in Medina in 626 (4 AH). The hadith collections preserve his grandfather's tenderness for the two brothers — "Hasan and Husayn are the chiefs of the youth of paradise," transmitted by al-Tirmidhi; the Prophet lengthening his prostration because a grandson had climbed his back; "Husayn is from me and I am from Husayn," in the Musnad of Ahmad and al-Tirmidhi. He was a child of seven at the Prophet's death, and stood under the cloak in the hadith of the mantle in Sahih Muslim.

Through the caliphates of Abu Bakr, Umar, and Uthman he lived as a member of the Prophet's house in Medina; at the siege of Uthman's house he was among the young men set at the door. He fought beside his father at the Camel, Siffin, and Nahrawan, and accepted — with recorded reluctance — his brother Hasan's treaty with Mu'awiya in 661, keeping its terms until Mu'awiya's death. When Yazid succeeded his father in 680 and demanded allegiance, Husayn refused, left Medina for Mecca, and answered the letters of Kufa's Shia with a mission of his cousin Muslim ibn Aqil — who was betrayed and executed. Proceeding toward Kufa with his family and a small band, he was intercepted, and on 10 Muharram 61 AH (October 680) was killed with his sons, brothers, and companions — seventy-odd men — at Karbala, thirsty, after refusing to the last to pledge to Yazid. The women and his surviving son Ali (Zayn al-Abidin) were taken captive to Kufa and Damascus. Al-Tabari, drawing on the early account of Abu Mikhnaf, preserves the day in detail. His body lies at Karbala; the resting place of his head is itself a matter of divergent traditions, claimed at Cairo, Damascus, and Karbala.

Husayn's defining struggle was the refusal of allegiance to Yazid — for the Shia tradition, the stand of guidance against usurpation; in the broad Sunni reading, a grandson of the Prophet's principled refusal of an unworthy and impious ruler. His own transmitted words frame it as reform, not rebellion: the letter to the Banu Hashim and the declaration, preserved in the maqtal literature and al-Tabari, that he rose "not out of insolence or pride… but to seek the reform of my grandfather's community, to command right and forbid wrong."

The march itself was a passage of narrowing choices: the death of Muslim ibn Aqil, the desertion of most fellow travelers when the news came, al-Hurr's cavalry forcing the caravan away from Kufa's wells, the arrival of Umar ibn Sa'd's army, and the night of Ashura when — the sources record — he released his companions from their allegiance, and none who remained would leave. The thirst of the encircled camp, the fall of his kin one by one — his son Ali al-Akbar, his nephew al-Qasim, his brother al-Abbas cut down seeking water, the infant Abdallah killed in his arms — form, in the transmitted accounts, the passion that Muharram has commemorated ever since.

What Husayn taught, he taught mostly by the manner of his death, and both traditions have drawn the lesson: that allegiance cannot be compelled, that a community's reform may be worth a life, and that dignity under overwhelming force is itself a form of victory. His transmitted sayings run in that grain — among the most cited, from the field of Karbala: "If you have no religion, then at least be free in this world of yours." His du'a of Arafa, transmitted in the Shia devotional corpus, remains one of the tradition's great prayers.

The hadith collections preserve his grandfather's testimonies as his standing rank: chief of paradise's youth, beloved of the Prophet, one of the people of the cloak. In Shia Islam he is the third Imam, ma'sum, and the door of salvation — "Husayn is the lamp of guidance and the ark of salvation," in the tradition's transmitted words. In Sunni Islam he is the master-martyr of the Prophet's house; the scholarship of both traditions condemned his killing, and later Sunni authorities — Ibn Kathir's al-Bidaya among them — recorded the day as an atrocity while cautioning against retrospective cursing wars.

Husayn's early arms were in his father's wars — the Camel, Siffin, Nahrawan — and, the histories record, in campaigns of the conquest era. But Karbala is his battle. The accounts transmitted through Abu Mikhnaf in al-Tabari describe the tenth of Muharram hour by hour: the refusal of the final ultimatum, the morning prayer under arrows, the single combats, the killing of the male kin down to the infant, and Husayn's own end — struck down, by the most transmitted account, by Sinan ibn Anas, with Shimr ibn Dhi al-Jawshan named over the severing; the camp plundered, the tents fired, the survivors marched to Ibn Ziyad in Kufa and on to Yazid in Damascus.

The aftermath was war by other means: the penitents (Tawwabun) of Kufa rose in 684 and died at Ayn al-Warda; al-Mukhtar's rising of 686 hunted down the killers named in the maqtal accounts; and the memory of Karbala became, for every later Shia rising and for rebels of many stripes, the permanent argument against tyranny.

The wrong of Karbala is not itself disputed between the traditions — classical Sunni and Shia scholarship alike condemn the killing of the Prophet's grandson. What the traditions weigh differently is its meaning and its assignment of guilt. Shia Islam reads Karbala as the cosmic crime: the designated Imam martyred by the usurping state, Yazid accursed, the day of Ashura the axis of the religious year, mourned with weeping, majalis, and pilgrimage. Sunni assessments condemn Yazid's forces and generally Yazid's conduct, while dividing — as the classical texts of Ibn Kathir and al-Ghazali's discussions attest — over whether cursing Yazid by name is permitted, and over how far the Kufan invitations that summoned then abandoned Husayn share the blame.

Documented subsidiary disputes include the responsibility of Ibn Ziyad versus Yazid's direct orders (the sources transmit both claims); the authenticity of individual episodes and speeches in the later maqtal literature beyond the early core of Abu Mikhnaf; the resting place of the head; and the permissibility of the mourning rites themselves, debated between and within the traditions. All are presented here as the sources and traditions carry them.

Karbala reshaped Islam's conscience more than any event after the Prophet's death. For Shia Islam it is the constitutive tragedy: Muharram and Arbaeen — the latter today among the largest annual pilgrimages on earth, to his shrine at Karbala — organize the community's year, and "every day is Ashura, every land is Karbala" its transmitted watchword. For Sunni Islam, Husayn is the beloved martyr of the Prophet's house whose death stands as the permanent proof that legitimacy is not mere power. Beyond Islam, his stand has been claimed by movements of conscience from the Indian independence struggle onward — Gandhi's tribute to Husayn's example is frequently cited.

Through his son Zayn al-Abidin, sole adult male survivor of the day, descend the later Imams of the Shia and countless sayyid lines. The shrine city of Karbala and the Ashura minbar in every land keep the account of 10 Muharram 61 in living recitation — the rare case of a seventh-century day preserved, year by year, in the world's collective observance.
