From an Islamic perspective, atheism is considered a grave sin known as shirk (association of partners with God; Allah). 🏵️🏵️
The Quran describes it as the greatest injustice one could do to oneself, stating, "And whoever associates others with Allah – it is as though he had fallen from the sky and was snatched by the birds or the wind carried him away to a far-off place" [22:31].
It is a rejection of the belief in the existence of Allah, and as such, it is inherently considered a severe moral and spiritual deficiency.

Islam teaches that belief in Allah and adherence to His commandments is the foundation of moral and ethical behavior.
The Prophet Muhammad (peace be upon him) said, "The best of deeds is to believe in Allah and His Messenger" [Bukhari].
Faith in Allah drives an individual to be responsible and accountable for their actions, thereby guiding them to engage in good deeds and avoid evil.

Islam teaches that human beings have been given free will and the ability to choose between right and wrong.
Therefore, even if a person does not believe in Allah, they will be held accountable for their actions in this world and will face the consequences of their behavior.
The Quran states, "And whoever does righteous deeds, whether male or female, while being a believer – those will enter Paradise and will not be wronged, [even as much as] the speck on a date seed" [4:124].

Islam emphasizes the importance of upholding moral values, such as honesty, justice, compassion, and respect for human life, regardless of whether or not one believes in Allah.
The Quran states, "Indeed, the most noble of you in the sight of Allah is the most righteous of you. Indeed, Allah is Knowing and Acquainted" [49:13].
The Prophet Muhammad (peace be upon him) also emphasized the importance of good character by saying, "I have been sent to perfect good character" [Musnad Ahmad].

In the end, from an Islamic perspective, atheism is considered a severe sin that contradicts faith in Allah and is a deficiency in both spiritual and moral values. Nonetheless, Islam acknowledges the existence of free will and holds all human beings accountable for their actions, regardless of their belief system, thereby emphasizing the importance of upholding good moral values and engaging in righteous deeds.
