Ayub Ali made his way to London via the US, having jumped ship there in 1919. He set up the Shah Jolal Restaurant at 76 Commercial Street, in the heart of the East End. The café served as a hub for the Indian community there. In their interviews recorded in Caroline Adams’ book, the early Sylhet migrants to Britain describe Ali in glowing terms. According to them, he took care of lascars who had jumped ship and were in breach of their contract and therefore wanted by the ship companies. He gave them free food and shelter and helped them register at India House and the local police station. When they got jobs, many would go on to rent rooms in his house in Sandys Row, known locally as ‘Number Thirteen’, where they would continue to receive support from Ali in the form of letter reading and writing, and help with remittances to India. He was known by them as ‘Master’.

Ali formalized his social welfare work among lascars when he founded the Indian Seamen’s Welfare League with Shah Abdul Majid Qureshi in 1943. The organization had its office in Christian Street and its stated aim was ‘to look after the economic, social and cultural interests of Indian seamen, to provide them with recreation in Great Britain and to communicate with their relatives in India in the event of any misfortunes befalling them’ (L/PJ/12/630, p. 140). Ali was also involved with the East End branch of the India League (serving as treasurer at one point) whose meetings were frequently held in his café, and is recorded as present at the 1943 protest meeting of the Jamiat-ul-Muslimin at their dismissal from the East London Mosque by its trustees. He was also president of the UK Muslim League, reportedly mixing with Liaquat Ali Khan and Jinnah. He went on to start up a travel agency business, Orient Travels, at 13 Sandys Row, which later moved to 96 Brick Lane.
