Imam Ali ibn Husayn ibn Ali ibn Abi Talib (الإِمَامُ عَلِيُّ بنُ الحُسَيِّ; 658-713 CE; 38-95 AH; also called *Zayn al-'Abidin* — the ornament of the worshippers — and *al-Sajjad* — the one who prostrates much; the fourth Imam in the Ismaili chain after his father Imam Husayn) survived the massacre of Karbala (10 Muharram 61 AH) because he was gravely ill and unable to fight — a divine preservation of the Imamate chain. His survival, witnessed and confirmed by his aunt Zaynab bint Ali, was understood as the proof that the nass chain does not break: even when the battlefield slaughtered all other males of the family, the Imam's person was divinely protected. He went on to become one of the most revered figures in all of Islamic spiritual history — not for military campaigns or political governance, but for his worship, scholarship, and the extraordinary literary monument of the *Sahifa al-Sajjadiyya* (The Psalms of Islam), which contains his prayers and supplications and is considered one of the greatest works of Islamic literature.

Karbala and Survival

When Imam Husayn was martyred at Karbala on 10 Muharram 61 AH (680 CE), his son Ali was approximately 22 years old and severely ill — too ill to fight. This illness was later understood as divinely arranged: had he been healthy, he would have fought and died with the others, ending the Imamate chain.

After Karbala, he was taken captive with the women and children of the Prophet’s family and brought to Yazid’s court in Damascus. There, according to all accounts, he maintained his dignity and prophetic lineage with extraordinary composure — making clear speeches in court about the Ahl al-Bayt’s station.

Yazid eventually released the survivors, and Imam Ali Zayn al-‘Abidin returned to Medina, where he spent the rest of his life.


Character and Worship

His epithet Zayn al-‘Abidin (ornament of the worshippers) was given because of the extraordinary intensity of his worship. He was reported to have prayed 1,000 rak’at per day in voluntary prayer. When he made wudu and stood for prayer, his color would change from the gravity of the divine presence.

He was known for:


The Sahifa al-Sajjadiyya — The Psalms of Islam

His greatest legacy is the Sahifa al-Sajjadiyya (صَحِيفَةُ السَّجَّادِيَّة — the Page/Book of the Prostrating One) — a collection of 54 prayers covering every dimension of the believer’s relationship with Allah: morning prayers, evening prayers, prayers on the occasion of the new moon, prayers during illness, during Ramadan, prayers for parents, for neighbors, for enemies, for forgiveness.

The Sahifa is considered by Shi’a and Ismaili scholars as one of the most exalted works of Islamic literature after the Quran and the hadith corpus. Its Arabic is of extraordinary beauty and theological precision.


The Risalat al-Huquq — The Treatise on Rights

He is also the author of Risalat al-Huquq (the Treatise on Rights) — a systematic enumeration of the rights that different categories of people and conditions hold over the believer: rights of Allah, rights of the self, rights of parents, of children, of neighbors, of scholars, of rulers, of the poor. It is a comprehensive ethical framework unlike anything else in early Islamic literature. See [[risalat-huquq]].
