Izz ad-Din al-Qassam

Before there was a Palestinian national movement with parties, programmes, and recognised leadership, there was Izz ad-Din al-Qassam — the Syrian preacher who came to Haifa, worked among the poor workers and peasants who had flooded into the city from dispossessed rural communities, preached in the mosques, and quietly, systematically, built the first armed clandestine organisation in Palestinian history: small cells of workers and farmers who trained, acquired weapons, and prepared for the armed resistance that al-Qassam was convinced was both morally obligatory and practically necessary. He died before that resistance became the mass movement he had envisioned — shot down by British forces in the hills near Yaabed in November 1935, choosing death in battle over surrender. But his death did something his life had not yet accomplished: it ignited the Arab Revolt of 1936–1939, the mass Palestinian uprising that remains the largest sustained anti-colonial revolt in the Arab world's Mandate period. The rockets that Hamas fires from Gaza bear his name. The question of what he would have thought about how his legacy has been used is unanswerable, but the legacy itself — the first organiser of Palestinian armed resistance from below — is beyond dispute.

Jabla and al-Azhar: The Formation of a Preacher-Organiser

Izz ad-Din al-Qassam was born in 1882 in Jabla — a small coastal town on the Mediterranean shore of Syria, in the Latakia region that would later become the heartland of Alawi Syrian identity but that in the late Ottoman period was a mixed Sunni-Alawi-Christian coastal community. His family background was deeply religious: his father was a Qadiri Sufi sheikh, and the household was one in which Islamic learning, spiritual practice, and social engagement were inseparable. This formation — religion as a total way of life that encompassed ethics, social organisation, and political commitment rather than merely individual piety — would define al-Qassam's approach to everything that followed.

He received his advanced Islamic education at al-Azhar University in Cairo — the ancient institution that had been training Islamic scholars and jurists for a thousand years and that in the early twentieth century was also a centre of Islamic reformist thought, engaging with the questions of how Islamic societies should respond to European colonial domination and what Islamic tradition had to offer for the political and social challenges of modernity. Al-Qassam absorbed both the traditional scholarly curriculum and the reformist current — the influence of figures like Muhammad Abduh and Rashid Rida who were arguing that Islam needed to be recovered from the accretions of superstition and quietism that had weakened Muslim societies, and that genuine Islamic practice demanded active engagement with the world rather than passive resignation to its injustices.

He returned to Syria as a qualified Islamic scholar and preacher, settled in the Jabla area, and began organising — preaching, teaching, building the kind of community religious organisation through which an Islamic scholar of his training and ability could exercise real social influence. He was also, from early in his Syrian career, politically engaged: when French forces occupied Syria after the First World War and suppressed the Arab Kingdom of Syria that had briefly existed in Damascus, al-Qassam participated in armed resistance to the French occupation in the Latakia region before French military pressure forced him into exile. He arrived in Palestine approximately 1920–1921, expelled from his homeland as Sultan al-Atrash's revolt against French authority in the Druze Mountain was still being organised.

Haifa and the Working Poor: Building from Below

The Haifa that al-Qassam arrived in around 1921 was a city undergoing rapid and disorienting transformation. The British Mandate had turned Haifa into Palestine's primary port and industrial city — the terminus of the railway to Damascus and beyond, the site of the new oil pipeline terminus from Iraq, a commercial and industrial hub that was attracting waves of Arab peasants from the surrounding countryside who had been displaced from their land by Jewish land purchases and who were arriving in the city as impoverished workers seeking any available employment. These men — uprooted from their villages, living in the crowded poor quarters of the city, cut off from the social structures of village life, experiencing the colonial economy's most direct and personal impact — were al-Qassam's congregation and his organisational base.

He served as imam of the Istiqlal Mosque in Haifa's Halissa neighbourhood — the working-class quarter where many of the displaced peasant workers lived — and built a social presence that went far beyond conventional mosque leadership. He performed marriages and registered them for the Islamic court, giving him a legitimate reason to enter the homes of the working-class community and to know its members personally. He taught in religious schools and in informal educational sessions for workers who had little or no formal education. He founded the Young Men's Muslim Association, which provided a legitimate public organisational framework for the youth of the community. Through all of these activities he built the network of personal trust and social connection that was the precondition for the clandestine political organisation he was simultaneously developing.

The contrast between al-Qassam's social base and that of the Palestinian notable leadership — the educated urban families like the Husaynis who dominated Palestinian politics through their control of Islamic institutions, land, and political connections — was fundamental and deliberate. Al-Qassam was building from below: from the workers and displaced peasants who constituted the majority of the Palestinian Arab population but who had no effective voice in the notable-dominated Palestinian political institutions of the Mandate period. His relationship with these communities was not that of a patron dispensing favours from above but of a preacher and organiser who lived among them, knew their conditions from daily proximity, and understood their grievances in the most concrete possible terms.

The Secret Organisation: Cells, Weapons, and the Long Preparation

From approximately the late 1920s, al-Qassam was building an armed clandestine organisation among the workers and peasants of the Haifa area and the surrounding villages — small cells of trusted men who acquired weapons, trained in their use, and prepared for armed resistance to the British Mandate and Zionist immigration. The organisation was structured for security: cells were kept small, members knew only their immediate cell rather than the broader organisation, and the compartmentalisation that experience with French colonial intelligence in Syria had taught him was maintained as strictly as conditions allowed.

His organisational methodology was grounded in his Islamic scholarly training: the argument that armed resistance to colonial occupation and the displacement of Muslim peoples from their land was a religious obligation — a form of jihad in the classical Islamic legal sense of armed defence of Muslim territory against aggression — gave the organisation both its ideological framework and its recruitment mechanism. The men he was recruiting were not secular nationalists drawn by political ideology; they were Muslim workers and peasants who understood their situation in the religious terms that al-Qassam's preaching made available to them, and who found in the obligation of religious resistance a framework for understanding and responding to the dispossession they were experiencing.

The organisation conducted a series of attacks on Jewish settlers and British officials in 1931–1935, establishing its operational capacity while maintaining the secrecy that prevented British authorities from identifying and arresting its leadership. Al-Qassam was planning a more systematic and large-scale armed uprising — a transition from the sporadic attacks of the early 1930s to a coordinated armed movement that could sustain operations across a wider area — when events moved faster than his preparation.

Yaabed: The Choice That Made a Martyr

In November 1935, a British police search operation — triggered by the discovery of a weapons cache connected to al-Qassam's network — located his group in the hills near Yaabed in the Jenin district. Al-Qassam had fled Haifa with a small group of followers when it became clear that British authorities were closing in, intending to take to the hills and begin the armed uprising he had been preparing. Instead, he found himself surrounded.

Faced with the choice between surrender and fighting, al-Qassam chose to fight. He was not a young man seeking glory — he was fifty-three years old, a scholar and preacher who had spent fifteen years building an organisation precisely to avoid this kind of premature exposure. But he had also spent those fifteen years teaching his followers that armed resistance to colonial occupation was a religious obligation, that martyrdom in such resistance was honourable, and that submission to an unjust authority was not an option that Islamic ethics permitted. When the moment came, he was not willing to contradict through his own actions the teaching he had given to others.

He was killed in the firefight on 20 November 1935. Several of his followers were also killed; others were captured. British forces reported killing a significant armed group; Palestinian observers noted that the group had chosen death over surrender. The news reached Haifa and spread across Palestine within hours, and its effect was immediate and electric: the man who had preached armed resistance had died practising it, and the Palestinian political landscape was transformed by his martyrdom in ways that fifteen years of his preaching and organising had not achieved.

The Martyrdom That Triggered a Revolt

Al-Qassam's funeral in Haifa drew enormous crowds — tens of thousands of Palestinians from the city and surrounding villages who came to mourn and to demonstrate, in their numbers, the depth of the anger and grief that his death had ignited. The Palestinian press turned him immediately into a national martyr; political figures who had had no connection to his organisation publicly honoured his memory; and the outrage at his killing combined with the pre-existing Palestinian anger over land sales, Jewish immigration, and British Mandate policy to produce the political pressure that erupted in the Arab Revolt of April 1936.

The Arab Revolt of 1936–1939 — which began with a general strike in April 1936 and escalated into armed insurrection across rural Palestine — was not directly organised by al-Qassam's network; most of his closest followers had been killed or captured at Yaabed or in the subsequent British crackdown. But it was inspired by his example and fuelled by the moral authority his martyrdom had given to the argument that armed resistance was both necessary and righteous. The revolt's military commanders — including Fawzi al-Qawuqji, who entered Palestine with his volunteer column in 1936 — explicitly invoked al-Qassam's memory as the spirit of what they were continuing.

The causal connection between al-Qassam's death and the Arab Revolt is direct enough that historians regularly describe the revolt as the delayed expression of the movement he had been building — the mass uprising that came five months after the leader who had been organising it for fifteen years was killed before he could launch it himself. In this sense, his martyrdom accomplished in death what his organisation had been working toward in life, though not in the form he had planned or under the leadership he had developed.

Legacy: The Name That Endures

Izz ad-Din al-Qassam's legacy extends across the entire spectrum of Palestinian political tradition in a way that is unusual and revealing. Secular nationalists in the Fatah tradition honour him as the founder of Palestinian armed resistance — the first organiser who brought the struggle to the Palestinian masses rather than conducting it through notable-class politics. Islamists in the Hamas tradition claim him as the prototype of Islamic resistance — the Islamic scholar who demonstrated that armed resistance to colonial occupation was a religious duty, not merely a political choice. The Qassam Brigades that bear his name and the rockets named for him are Hamas's direct continuation of what it regards as his legacy.

Whether al-Qassam would have recognised himself in the Hamas tradition is a question that cannot be answered — he died in 1935, decades before the ideological movements that would claim his inheritance were formed. What can be said is that the specific combination he represented — Islamic religious authority, social work among the dispossessed, clandestine armed organisation, and willingness to die for what he believed — established a template for Palestinian resistance that has proven extraordinarily durable across nine decades and multiple ideological transformations of the movements that claim to continue his work.

He was not a theorist or a strategist in the formal sense — he left no systematic political writings that articulate a political programme. What he left was an example: of a preacher who took his own preaching seriously enough to act on it, of an organiser who built from the bottom of society rather than from the top, and of a man who chose death over surrender at the moment when surrender was the only alternative. Palestine has built an entire tradition of resistance on that example, and it shows no signs of forgetting the man who set it.
