What is atheism, and what are the divisions among its followers?
Atheism means denying God, the occult, prophecies, the resurrection, and reckoning.
Atheism has many sects and various doctrines. There are:
Atheists: people who deny the existence of God and reject religious beliefs
Deists: People who believe in the existence of God but disbelieve in religions.
Agnostics: People who cannot be sure of the validity of God's existence but can not be sure that he does not exist
Apatheists: people who are not interested in whether God exists or not.
Humanists: people who base their understanding of the world on reason and science, rejecting god's existence, divine beliefs, or occults
These are the most famous divisions of contemporary atheistic doctrines.
All the followers of these divisions can be called irreligious: the atheist, the deist, the agnostic, the apatheist and the humanist are all irreligious, while the humanist may be non-atheist.
Important Note:
The occurrence of the word atheist in history books does not mean the contemporary terminological concept of atheism, which means the denial of God and prophecies, but rather a kind of deviation in one of the parts of the faith, such as names and attributes.
Therefore, whoever said that Ibn Sina or any of the Muslim philosophers was an atheist and attributed it to atheism in its contemporary terminological sense was wrong, because none of these was an atheist by the contemporary terminological definition of atheism. But some of them had a defect in some doctrinal issues.

Utter nonsense. Atheism is just not believing in God.
