The Jamiat-ul-Muslimin, based at the East London Mosque, was a charitable society for the promotion of Islam, founded in 1934. It membership consisted predominantly of working-class lascars, peddlers and other workers who inhabited the East End of London. The Jamiat’s stated objectives were: ‘To serve the cause of Islam truly and practically by creating facilities for the observance of its Principles: to produce a weekly paper…to collect funds for a Mosque in the East End of London: to provide for the training and education of Muslims generally; to succour poor and needy Muslims: to promote social intercourse between resident Muslims and visitors to this country and generally to adopt all practical and legitimate means to work for the moral, intellectual and economic advancement of Muslims throughout the world’ (L/PJ/12/468). Thus, its objectives combined faith with the social and political. The organization first came to notice by government authorities in 1938 when it staged a protest against H. G. Wells’ A Short History of the World. The Jamiat organized a march to India House, Aldwych, where a deputation presented a petition to the High Commissioner for India, Firoz Khan Noon.

Before the establishment of the East London Mosque in 1941, the organization’s members would gather and worship at King’s Hall in Commercial Road. The Jamiat played a key role in the establishment, inauguration and management of the mosque. In 1943 they were involved in a dispute with the trustees of the mosque, claiming that they should have ultimate control over its management and affairs. There were also active branches of the Jamiat in Glasgow, Cardiff, Manchester, Liverpool and Birmingham.
