Muhammad Iqbal sought an Islamic revival based on social justice ideals and emphasized traditional rules, e.g. against usury. He argued strongly that dogma, territorial nationalism and outright racism, all of which were profoundly rejected in early Islam and especially by Muhammad himself, were splitting Muslims into warring factions, encouraging materialism and nihilism. His thought was influential in the emergence of a movement for independence of Pakistan, where he was revered as the national poet. Indirectly this strain of Islam also influenced Malcolm X and other figures who sought a global ethic through the Five Pillars of Islam. Iqbal can be credited with at least trying to reconstruct Islamic thought from the base, though some of his philosophical and scientific ideas would appear dated to us now. His basic ideas concentrated on free-will, which would allow Muslims to become active agents in their own history. His interest in Nietzsche (who he called 'the Wise Man of Europe') has led later Muslim scholars to criticise him for advocating dangerous ideals that, according to them, have eventually formed in certain strains of pan-Islamism. Some claim that the Four Pillars of the Green Party honor Iqbal and Islamic traditions.
Fazlur Rahman was professor of Islamic thought at the University of Chicago and McGill University, and an expert in Islamic philosophy. Not as widely known as his scholar-activist contemporary Ismail Raji al-Faruqi, he is nonetheless considered an important figure for Islam in the 20th century. He argued that the basis of Islamic revival was the return to the intellectual dynamism that was the hallmark of the Islamic scholarly tradition (these ideas are outlined in Revival and Reform in Islam: A Study of Islamic Fundamentalism and his magnum opus, Islam). He sought to give philosophy free rein, and was keen on Muslims appreciating how the modern nation-state understood law, as opposed to ethics; his view being that the shari'ah was a mixture of both ethics and law. He was critical of historical Muslim theologies and philosophies for failing to create a moral and ethical worldview based on the values derived from the Qur'an: 'moral values', unlike socioeconomic values, 'are not exhausted at any point in history' but require constant interpretation. Rahman was driven to exile from his homeland, Pakistan, where he was part of a committee which sought to interpret Islam for the fledging modern sovereign state. Some of his ideas from English (which he claimed were from the Islamic tradition) were reprinted in Urdu and caused outrage among conservative Muslim scholars in Pakistan. These were quickly exploited by opponents of his political paymaster, General Ayyub Khan, and led to his eventual exile in the United States.

Abdul Rauf is a highly visible American-Egyptian Imam at New York's Masjid al-Farah in addition to being Founder and Chairman of Cordoba Initiative, a non-profit organization seeking to bridge the divide between the Muslim world and the West.
Morteza Motahhari was a lecturer at Tehran University. Motahhari is considered important for developing the ideologies of the Islamic Republic. He wrote on exegesis of the Qur'an, philosophy, ethics, sociology, history and many other subjects. In all his writings the real object he had in view was to give replies to the objections raised by others against Islam, to prove the shortcomings of other schools of thought and to manifest the greatness of Islam. He believed that in order to prove the falsity of Marxism and other ideologies like it, it was necessary not only to comment on them in a scholarly manner but also to present the real image of Islam.
Ali Shariati was a sociologist and a professor of Mashhad University. He was one of the most influential figures in the Islamic world in the 20th century.

Shariati was also deeply influenced by Mowlana and Muhammad Iqbal.
Musa al-Sadr was a prominent Shi'a Muslim intellectual and one of the most influential Muslim philosophers of 20th century. He is most famous for his political role, but he was also a philosopher who had been trained by Allameh Tabatabaei. As Professor Seyyed Hossein Nasr said: "his great political influence and fame was enough for people to not consider his philosophical attitude, although he was a well-trained follower of long living intellectual tradition of Islamic Philosophy". One of his famous writings is a long introduction for the Arabic translation of Henry Corbin's History of Islamic Philosophy.
Hossein Nasr, a political ecologist, argues that the concept of the Khilafah (Islamic caliphate) is fundamentally compatible with ideals of the ecology movement and peace movement, more so than expressed through conventional interpretations of Islam. He argues for an ecology-based ecumenism that would seek unity among the faiths by concentrating on their common respect for life as a Creation, i.e. the Earth's biosphere, Gaia, or whatever name. Pope John Paul II has made similar suggestions that "mankind must be reconciled to the Creation", and there is a Parliament of World Religions seeking a "global ethic" on similar grounds.
Muhammad Baqir al-Sadr was an Iraqi Shi'a cleric, a philosopher, and ideological founder of Islamic Dawa Party born in al-Kazimiya, Iraq. Mohammad Baqir Al-Sadr's political philosophy, known as Wilayat Al-Umma (Governance of the people), set out his view of a modern day Islamic state. His most famous philosophical works include: Falsafatuna (Our Philosophy), in which he refutes modern Western philosophical schools and asserts an Islamic view, Iqtisaduna (Our Economy), consisting of an exegesis of Islamic economics coupled with a critique of Western political economy as manifested in the Soviet Union on one hand and the United States on the other, and Al-Usus al-Mantiqiyyah lil-Istiqra' (The Logical Basis of Induction) in which he develops a theory which allows one to reach certainty through inductive methods.
