Since his death, a memorial lecture series has been established at Hampshire College in his honour. Speakers have included Kofi Annan, Edward Said, Noam Chomsky, and Arundhati Roy. Ahmad was admired as "an intellectual unintimidated by power or authority". He collaborated with such left-wing journalists, activists, and thinkers as Chomsky, Said, Howard Zinn, Ibrahim Abu-Lughod, Richard Falk, Fredric Jameson, Alexander Cockburn and Daniel Berrigan. Ahmad influenced several left-leaning activists including Chomsky, Zinn, Abu-Lughod, Richard Falk, Pervez Hoodbhoy, Cockburn, Said and Roy. Ahmad is credited for his insight into Islamic terrorism; he publicly criticised global support for the Islamic fundamentalist groups in Afghanistan.
