Islamic socialism is a political philosophy that incorporates elements of Islam into a system of socialism. As a term, it was coined by various left-wing Muslim leaders to describe a more spiritual form of socialism. Islamic socialists believe that the teachings of the Qur'an and hadith, citing aspects of the religion like zakat, are not only compatible with principles of socialism, but also very supportive of them.
Some early figures in Islam, such as Abu Dharr al-Ghifari, a companion of Muhammad, and the first Caliph, Abu Bakr, are sometimes regarded as forerunners of Islamic socialism for their advocacy of wealth redistribution. Interest in fusing Islam and socialism emerged in the nineteenth century, with Islamic Reformist thinker Jamal al-Din al-Afghani, whose writings on the topic were published in the 1930s and influenced many later thinkers. Social movements such as the Wäisi movement in Tatarstan, in the Russian empire, similarly drew on Islamic and socialist thought. In the twentieth century, the Indian Deobandi scholar Ubaidullah Sindhi, the Movement of God-Worshipping Socialists in Iran, the Muslim League in Pakistan, and the Iranian scholar Ali Shariati are among those to play a role in the history of the ideology.
