In 1908, he married Siti Murbiyah, daughter of Kyai Haji Muhammad Ilyas.
In 1909 he spent time in Mecca where he was exposed to ideas of Islamic reform being espoused by Rashid Rida, Mohammed 'Abduh, and others. He studied under Ahmad Khatib al-Minangkabawi, an influential Minangkabau Islamic teacher who was then resident in Mecca. During his time there he also befriended other students of his generation, such as Mas Mansoer, who would also later return to the Indies and play an important role in Islamic educational reform.
During the 1910s, after returning to Java, Abdul Halim founded a number of Islamic organizations, including Madjisul 'Ilmi (1911), Hayatul Qulub (1912) and Persyarikatan Ulama (1916).

Of the 62 members of the committee, he was in a group of eleven representing an Islamic faction, which also included Haji Agus Salim, Sukiman, Abdurrahman Baswedan.
In the following year, he was also appointed to the Central Indonesian National Committee, a consultative body meant to advise the president of Indonesia as the country was gaining its independence. During the Indonesian National Revolution in 1946–7, he was also involved in leading guerilla forces against the Dutch in his home region of Majalengka.
In 1955, Abdel Halim was a founding member of the Persatuan Ummat Islam.
