The ideology of communism
Question

                What is the philosophy whose slogan is “There is no God and everything is material”?
Praise be to Allah.
    This 
    is one of the slogans of communism, which is an ideology that is 
    materialistic in nature and in its ideas, methodology and philosophy. It 
    also has other slogans that are indicative of deep adherence to materialism, 
    to the point of atheism, such as “The only way to unite the world is on the 
    basis of materialism”, “Matter existed before thought”, “There was never a 
    time when matter did not exist”, “Man is the product of matter”, “Thought is 
    the product of the brain, and the brain is the product of matter.” 

    The 
    one who thinks that communism – or, more precisely, socialism – is merely a 
    school of economic thought is mistaken. Rather it is a philosophy that is 
    materialistic in the way in which it explains influential factors and the 
    nature of society, and it relies on dialectics in the way it explains 
    history. 

    The 
    best theory with regard to its origins is that it is one of the ideas that 
    were formed in Western minds as a result of the conflict with the church and 
    the clergy throughout many centuries, when oppression, suppression and 
    tyranny were the hallmarks of that period. Hence atheism, secularism, 
    communism, capitalism and other ideologies emerged as alternatives to the 
    long centuries of the Dark Ages; they took over those societies and are 
    still ruling them. Indeed they have become methodologies and ways of 
    thinking, and philosophies in which their followers believe, and on the 
    basis of which the thinkers developed theories. 

    
    Scholars and thinkers have written a great deal about the materialism of 
    communism. Here we will quote some of the most prominent and clearest things 
    that have been written, so that we may reach a brief definition of this 
    principle. 

    In 
    al-Mawsoo‘ah al-Muyassarah fi’l-Adyaan wa’l-Madhaahib wa’l-Ahzaab al-Mu‘aasirah 
    (p. 929-934) it says:

    Definition

    
    Communism is a school of thought based on atheism and the belief that matter 
    is the basis of all things. It explains history in terms of class conflict 
    and economic forces. 

    It 
    appeared in Germany at the hands of Marx (d. 1883) and Engels (d. 1895), and 
    was manifested in the Bolshevik revolution which occurred in Russia (1917) 
    at the instigation of the Jews. It expanded at the expense of other 
    ideologies, by force. Lenin (d. 1924) is the one who put communism into 
    practice, followed by Stalin (d. 1953), the secretary of the Communist 
    Party.

    Main ideas and beliefs

    -
    
    Denial of the existence of God and the unseen in general, and 
    belief that matter is the basis of all things.

    -
    
    They explain history in terms of conflict between the 
    bourgeoisie and proletariat (the capitalists and the poor). According to 
    their view, conflicts will end with the dictatorship of the proletariat.

    -
    
    They oppose all religions and regard them as the opiate of 
    the masses and servants of capitalism, imperialism and exploitation.

    -
    
    They oppose private ownership and say that all wealth should 
    be held in common between people and that inheritance should be abolished.

    -
    
    Every change in the world, according to their view, is the 
    inevitable result of changes in the means of production, and that thought, 
    civilization and culture are the products of economic development.

    -
    
    They say that morality is relative and is a reflection of the 
    means of production.

    -
    
    They believe that there is no hereafter, no punishment, and 
    no reward except in the life of this world.

    -
    
    In their view, the ends justify the means

    Lenin 
    said: “Destruction of three quarters of the world is nothing; what matters 
    is that the remaining quarter become communist.”

    Spread and areas of influence

    
    Communism has ruled a number of countries, including the Soviet Union, 
    China, Czechoslovakia, Hungary, Bulgaria, Poland, East Germany, Romania, 
    Yugoslavia, Albania and Cuba 

    
    Collapse of Marxism 

    
    Communism collapsed in its strongholds after seventy years of communist 
    rule, and after forty years of application of its ideas in Eastern Europe. 
    Senior officials in the Soviet Union, before its dismantling, announced that 
    many Marxist principles were no longer fit to remain and were unable to deal 
    with the problems and requirements of modern times. Everyone was convinced 
    that it is a corrupt theory. It is impossible to apply, because it carries 
    within itself the seeds of its own destruction. One of the greatest critics 
    of Marxism among the Marxists themselves is the American philosopher Eric 
    Mizom in his book The Sound Society; others among non-Marxists 
    include Karl Popper, the author of The Open Society, and others. Then 
    Gorbachev came along with his book Perestroika (Reconstruction), 
    in which he exposed the problems in the application of communism in the 
    Soviet Union. End quote. 

    To 
    sum up, the principles of communism are principles based on disbelief (kufr), 
    and it is not permissible for any Muslim to believe in them or embrace them, 
    or to join those who believe in them. A fatwa to that effect was issued by 
    the Islamic Fiqh Council of the Muslim World League, which you can see by 
    following

    And 
    Allah knows best.
