Imam Sajjad was born in Medina around 658 CE, the son of Imam Husayn. According to an account common in Shia sources, his mother was ShahrbanuAccording to an account common in Shia sources, the daughter of Yazdegerd III, the last Sasanian king of Iran, and the mother of Imam Sajjad. The historical accuracy of this account — including her very identity and existence — is seriously disputed among historians and academic researchers., the daughter of the last Sasanian king of Iran, though the historical accuracy of this account is disputed among researchers. Imam Sajjad was present at Karbala in 680 CE, then around twenty-two years old, where his father and most of the men of his family were martyred, but was too ill to fight and survived that day's massacre; as a result, he was Imam Husayn's only surviving son to carry the Imamate forward. After Karbala, he was taken captive along with the surviving family to Kufa and then Damascus, before YazidYazid ibn Muawiya, Muawiya's son and successor, who — contrary to the terms of Imam Hasan's peace treaty — was chosen as the second Umayyad caliph after his father's death.. After his release, he spent the rest of his life in Medina, away from politics and armed conflict, devoted to worship and teaching; this earned him the names Zayn al-Abidin (ornament of the worshippers) and al-Sajjad (the one who prostrates often). He died in 712 CE, around age fifty-four — poisoned, according to Shia belief — and was buried in the BaqiBaqi al-GharqadThe main cemetery of Medina, near the Prophet's Mosque, where many of Muhammad's companions are buried, along with Imam Hasan and several other Shia Imams. cemetery in Medina.
Hadiths
Spirituality
Praise be to God, the First with no first before Him, the Last with no last after Him.
This line opens the very first supplication of the Sahifa Sajjadiyya — a collection of 54 supplications by Imam Sajjad, considered one of the oldest and most authoritative devotional texts in Shia Islam, known as the "Psalms of the House of Muhammad." This first prayer, before any request at all, is devoted entirely to praising God.
The right of the tongue is that you keep it above vulgarity, accustom it to good, direct it toward proper conduct, and let it rest except where there's real need or benefit for your religion or your worldly life.
This line comes from Imam Sajjad's Risalat al-Huquq (Treatise on Rights) — a text that lists more than fifty distinct "rights": God's right over a person, the rights of one's own body parts over their owner, and the rights others hold over us. Many regard it as the earliest Islamic text on human rights in the broad sense of the term.
The right of your sight is that you lower it from what isn't permissible for you, and not use it carelessly except where it draws a lesson or gains you knowledge.
Another passage from the Risalat al-Huquq, this time on the right of sight. Imam Sajjad goes on to say that "sight is the gateway to drawing lessons" — meaning seeing should lead a person toward greater understanding, not just idle distraction.
The right of your father is that you know he is your origin, and that without him you wouldn't exist; so whatever pleases you in yourself, know that your father is the root of that blessing.
Another passage from the Risalat al-Huquq, this time on the right of a father — one that carried a particularly personal weight for Imam Sajjad himself, who lost his own father, Imam Husayn, at Karbala while still a young man.

Birth and a Persian Mother c. 658 CE
Imam Sajjad was born around 658 CE in Medina, the only son of Imam Husayn to survive into adulthood. According to an account found mostly in Shia sources, and especially prominent in Persian tradition, his mother was ShahrbanuAccording to an account common in Shia sources, the daughter of Yazdegerd III, the last Sasanian king of Iran, and the mother of Imam Sajjad. The historical accuracy of this account — including her very identity and existence — is seriously disputed among historians and academic researchers., daughter of Yazdegerd III, the last Sasanian king, who had been taken captive by the Muslims after the conquest of Iran. Many historians and academic researchers seriously doubt the historical accuracy of this account, particularly its details and her identity.
Karbala and the Illness That Saved His Life 680 CE
In 680 CE, Imam Sajjad, then around twenty-two, was present with his father Imam Husayn at Karbala, but according to the well-known account, he was suffering from a severe fever and could not take part in the fighting. This illness is why YazidYazid ibn Muawiya, Muawiya's son and successor, who — contrary to the terms of Imam Hasan's peace treaty — was chosen as the second Umayyad caliph after his father's death.'s forces refrained from killing him; as a result, he was the only surviving adult male of Imam Husayn's family that day.
Captivity and the Speech in Damascus 680–681 CE
After Ashura, Imam Sajjad, still around twenty-two, was taken captive along with the surviving family — including his aunt Zaynab bint AliA daughter of Imam Ali and Fatima and Imam Husayn's sister, present at Karbala. Afterward, in well-known speeches in Kufa and Damascus, she exposed Yazid's forces' conduct and protected the surviving members of the Prophet's household, including her nephew Ali ibn Husayn. — and marched first to Kufa and then to Damascus, before YazidYazid ibn Muawiya, Muawiya's son and successor, who — contrary to the terms of Imam Hasan's peace treaty — was chosen as the second Umayyad caliph after his father's death.. At YazidYazid ibn Muawiya, Muawiya's son and successor, who — contrary to the terms of Imam Hasan's peace treaty — was chosen as the second Umayyad caliph after his father's death.'s court, Imam Sajjad and Zaynab openly exposed the injustice of Karbala in a series of speeches; many historians believe these speeches played an important role in turning public opinion against YazidYazid ibn Muawiya, Muawiya's son and successor, who — contrary to the terms of Imam Hasan's peace treaty — was chosen as the second Umayyad caliph after his father's death.. The captives were eventually freed and allowed to return to Medina.
Return to Medina and Withdrawal from Politics 681–712 CE
After returning to Medina, Imam Sajjad, unlike some of his contemporaries — such as the leaders of the Tawwabun uprising and Mukhtar al-ThaqafiThe leader of an uprising in Kufa (685–687 CE) launched in the name of avenging Imam Husayn against those responsible for Karbala. Imam Sajjad, like other armed movements of his time, kept his distance from this uprising. in Kufa, who invoked vengeance for Husayn to justify armed revolt — withdrew from any political or military action. He chose this distance deliberately, devoting most of the rest of his life to worship, prayer, and teaching.
Zayn al-Abidin: Worship and the Sahifa al-Sajjadiyya 681–712 CE
Because of his round-the-clock worship and long prostrations, Imam Sajjad earned the names Zayn al-Abidin (ornament of the worshippers) and al-Sajjad (the one who prostrates often). His prayers, later compiled under the title Sahifa al-SajjadiyyaA collection of prayers attributed to Imam Sajjad, called the "sister of the Quran," regarded as one of the most important devotional and literary texts in Shia Islam., came to be called the "sister of the Quran" and remain one of the most important devotional and literary texts in Shia Islam.
The Treatise on Rights and His Students c. 690–712 CE
In a well-known treatise, the Risalat al-Huquqthe Treatise on RightsA treatise attributed to Imam Sajjad enumerating around fifty rights — from the right of God over human beings to the rights of neighbors, spouses, children, and even animals., Imam Sajjad enumerated around fifty rights — from the right of God over human beings to the rights of neighbors, spouses, and even animals — a work still cited in Islamic ethics today. He also trained students who later played a role in passing on the religious knowledge of the next generation of the Prophet's household.
Death and Succession 712 CE
Imam Sajjad died in Medina in 712 CE, around age fifty-four. Shia sources attribute his death to poisoning ordered by the reigning caliph, al-Walid ibn Abd al-MalikThe Umayyad caliph who ruled from 705 to 715 CE.

Open Historical Debates
The identity, and even the historical existence, of ShahrbanuAccording to an account common in Shia sources, the daughter of Yazdegerd III, the last Sasanian king of Iran, and the mother of Imam Sajjad. The historical accuracy of this account — including her very identity and existence — is seriously disputed among historians and academic researchers. as Imam Sajjad's mother and the daughter of Yazdegerd III is seriously disputed among historians and academic researchers; some regard it as a later, largely symbolic account that developed to link Persian identity with Shia Islam, rather than a documented historical report.
The account of Imam Sajjad's poisoning on the order of al-Walid ibn Abd al-MalikThe Umayyad caliph who ruled from 705 to 715 CE. Shia sources attribute Imam Sajjad's death in 712 CE to a poisoning ordered by him. is recorded in Shia sources, but like the poisonings attributed to Imam Hasan, this claim is treated with more skepticism in Sunni sources and academic scholarship.
The precise reason for Imam Sajjad's deliberate distance from the armed uprisings of his time, such as that of Mukhtar al-ThaqafiThe leader of an uprising in Kufa (685–687 CE) launched in the name of avenging Imam Husayn against those responsible for Karbala. Imam Sajjad, like other armed movements of his time, kept his distance from this uprising., is debated among historians: some see it as political caution in the face of Umayyad power, while others read it as a theological choice to focus on religious authority rather than direct political leadership.
Some accounts say Imam Sajjad's mother was the daughter of the last king of Persia -- but many historians look at this story with real doubt, since it appears mostly in later sources and may have grown up around a symbolic idea rather than a documented fact.
Shia sources say Imam Sajjad was poisoned on the order of the caliph, just like his uncle Imam Hasan is said to have been. Sunni sources treat this claim with more skepticism too.
Historians also debate exactly why Imam Sajjad stayed away from the armed uprisings of his time, like Mukhtar al-ThaqafiThe leader of an uprising in Kufa (685–687 CE) launched in the name of avenging Imam Husayn against those responsible for Karbala. Imam Sajjad, like other armed movements of his time, kept his distance from this uprising.'s revolt in Kufa. Some think it was political caution; others think he deliberately chose to focus on religious teaching rather than politics.
