See main: Islamic atheismIn Islam, atheists, among whom are mostly closet atheists (as open atheists in the Muslim world tend to be killed) are categorized as kafir (كافر), which carries connotations of blasphemy and disconnection from the Islamic community; a term, to note, that is also used to describe polytheists (shirk), and that translates roughly as "denier" or "concealer". In Arabic, "atheism" is generally translated ilhad (إلحاد), although this also means "heresy". (Ѻ). In the 14th century, the top three heretics or Islamic atheists were al-Marri (c.1020), aka the "Arab Lucretius", Ibn al Rawandi (c.870), a three impostors advocate, and Abu Hayyan (923-1023) (Ѻ), noted for his dialogue (Ѻ) on “why atheists do good work?” if, e.g., they have they have no fear of a final reckoning, do not seek to be rewarded by god or even expect even to return to god? The gist of their atheism rep was summarized as follows:
“The heretics in Islam are three: Ibn al Rawandi, Abu Hayyan al Tawhidi, and Abu Alaa al-Ma’arri–of them, mostly Abu Hayyan, because they (attempt to) edify grandiloquence but in fact they babble.”— Ibn al-Jawziyyah (c.1325)

Sheikh Mahmoud: Why did you become an atheist?
Ex-Muslim Atheist: Because there is no scientific evidence for god.
Muslim Host: How can you say that. Who created you? Who made you exist as a human being?
Sheikh Mahmoud: Do you know how you were created?
Ex-Muslim Atheist: There are many theories explaining our existence on this planet …
Sheikh Mahmoud: I’m asking you a question. How did you become a human being?
Muslim Host: How come you exist in this universe?
Ex-Muslim Atheist: Ok. Let me explain. There are theories that try to explain our existence. One theory is that god created us. Okay? But there are other theories, with much more evidence, like big bang theory.
Muslim Host: Speak Arabic! You are in Egypt. And you are addressing simple people, so don’t use big words for no reason.
Ex-Muslim Atheist: I’m using these terms because science is conducted in English.
Muslim Host: What science are you talking about, you are confusing and unreliable. You deny the existence of god and reject our religion and principles.
Ex-Muslim Atheist: Is this so bad?
Muslim Host: Of course, you come here to talk about a certain idea, but have nothing to offer. You offer atheism! You offer heresy! I apologize to the viewers for having an Egyptian of this kind on our show. I’m sorry, Mohammad, but you cannot stay with us on the show. Because your ideas are inappropriate, I’m sad to say. We cannot promote such destructive ideas. You have not uttered a single convincing word.
Sheikh Mahmoud: Look, dear Mohammad, you need psychiatric treatment. Many young people today suffer from mental illnesses, due to material or mental circumstances.
Muslim Host: It’s like Sheikh Mahmoud says, have you seen a psychiatrist? I advise you to leave the studio and go straight to a psychiatric hospital. You shouldn’t be here. Unfortunately, I cannot let you be here anymore. Please get up and leave, and I will continue the show with Dr. Mahmoud. Unfortunately, your ideas are destructive and bad for Egyptian youth. You are a bad example of Egyptian youth. … Mohammad, you can’t stay here. I advise you to go straight to a psychiatric hospital.

“Christianity and Islam made it illegal and immoral to think for a long time, and that’s why philosophy and science slumbered for centuries. That fact is proven by the simple fact that I could not find a philosophy book at a bookstore when I visited Istanbul, Turkey. Turkey is now a Muslim nation so it’s hard to find books by philosophers out on display at libraries or bookstores.”— Monydit Malieth (2013), The Future Affects the Past
