Al-Hadi ila’l-Haqq Yahya (859 – August 19, 911) was a religious and political leader on the Arabian Peninsula. He was the first Zaydiyya imam who ruled over portions of Yemen, in 897-911, and is the ancestor of the Rassid Dynasty which held intermittent power in Yemen until 1962. The Hadawiyya school of Islamic law, the only authoritarian one for the Zaydiyya, stems from him.


Yahya bin al-Husayn bin al-Qasim ar-Rassi was born in Medina, being a Sayyid who traced his ancestry from Hasan, son of Ali (and also grandson of Muhammad).[1] His grandfather al-Qasim ar-Rassi (d. 860), who unsuccessfully tried to reach political leadership, owned a property close to Mecca, ar-Rass. This is the origin of the name of the dynasty founded by Yahya, the Rassids.[2] Al-Qasim ar-Rassi was a major organizer of the theology and jurisprudence of the Zaydiyya division of the Shi’ites, which also had a following in Persia. The Zaydiyya hailed from Zaid (d. 740), second son of the fourth Shi'a imam Zayn al-Abidin. Yahya developed a theology based on his grandfather's teachings but gave it a more pronounced Shia profile. His positions were close to the contemporary Mu'tazila school in Iraq which emphasized reason and rational thinking. In 893 Yahya entered Yemen from the Hijaz, trying to build up a Zaydiyya power base in the area. His ambition was to rid the land from bad religious practices and bring the benefits of his own version of Islam. At this time the Tihamah lowland was ruled by the Ziyadid Dynasty (819-1018), originally governors of the Abbasid caliphs. In the interior, San'a was dominated by the indigenous Yu’firid Dynasty since 847.[3]

Acknowledged as imam[edit]


In a twist of alliances in 906, the imam joined forces with the Yu'firid ruler As'ad, in order to counter the clients of the Fatimids (who were later to rule Egypt). The new alliance soon proved fragile, however. San'a was taken by the Fatimid commander Ali bin al-Fadl who also dominated the Tihamah and the south. Ali soon renounced not only the Fatimids but also Islam itself. Eventually, in 910, al-Hadi resolved to establish his authority over San'a once again. He marched into the city without much opposition but soon left it to the Yu'firids. In the next year the imam died in Sa'dah. According to some, he was poisoned.[4] His tomb is adjacent to the al-Hadi mosque in Sa'dah, which is named after him and one of the oldest buildings of Islamic Yemen.[5] He was succeeded in his dignity by his son al-Murtada Muhammad.[6]


Although al-Hadi ila'l-Haqq Yahya was not always a successful ruler, he made a lasting impression on the tribal groups in the Yemeni highland, successfully propagating the Zaydi ideology of Islam - it has actually been argued that it was the Zaydis who seriously introduced Islam in Yemen.[7] Personally, he had the strength, courage and religious knowledge that were a prerequisite for the imamate. He was believed to have fought 70 battles, and was reportedly so strong that he could obliterate the stamp on a coin with his fingers. He saw himself as the restorer of Muslim beliefs, as seen from quotations of his works: "I revived the Book of God after it had perished", or "I revive the Book and the Sunna which have been rejected".[8] Al-Hadi’s religious teachings were in many respects strict, adhering to the school of his grandfather, Zayd bin Ali. He strove for a community where the imam, as the divinely designated leader, ensured the spiritual welfare of the people. For example, he expected women to be veiled, and soldiers to share the spoils in accordance to the Qur’an. He also tried to force the dhimmis of Najran to sell back any land they had bought in the Islamic period, but in the end he had to modify this.[9] Al-Hadi's subjects in the northern highland were not always content with the austere code of conduct that the imam tried to impose. Those who invited him had expected a prestigious mediator in their intratribal conflicts, rather than someone who tried to implement strict Islamic precepts. The career of al-Hadi (and of his successors) was therefore turbulent, as he tried to discipline rebellious and ostensibly sinful subjects.[10]
