Jamaat-e-Islami Pakistan
Nizami rose in the ranks of the East Pakistan branch of Jamaat-e-Islami Pakistan in the 1960s, having led the student organization, Islamic Chhatro Shango (now Islami Chhatro Shibir). After the independence of Bangladesh, Sheikh Mujibur Rahman, the first president, banned Jamaat from political participation as it had opposed the liberation war, and many of its members collaborated with the Pakistan Army during the conflict. Nizami and some other top leaders left the country.
