What is the ruling on studying philosophy which contains ideas that contradict Islamic Sharia, what is your opinion on the Mu'tazilah, and what should I do about this?

Most philosophy contradicts the religion of Islam, and indeed all heavenly books and messages, because it is based on polytheism. As Shaykh al-Islam Ibn Taymiyyah clarified, most philosophical books are "false, even outright disbelief."

It is forbidden for a non-specialist to study philosophy for fear of being influenced by its sophistries. However, for people of knowledge and religion who have specialized in it, there is no harm in studying it to distinguish truth from falsehood and to warn Muslims against it.

It states in the fatwas of the Permanent Committee: "If one is knowledgeable and confident in himself, not fearing temptation in his religion from reading it, nor from sitting with its proponents, and intends by reading it to refute the falsehood within it—in support of the truth—then it is permissible for him to study it for that purpose. Otherwise, it is forbidden for him to study it and associate with its proponents, to distance himself from falsehood and its people, and to avoid temptation."

It is advised for someone in an academic stage to switch to another major that does not include the study of philosophy if possible. Otherwise, they should seek Allah's help and complete their studies with caution against the misguidance of the people, seeking beneficial knowledge, arming themselves with piety, and striving in acts of obedience, reciting the Quran, and performing dhikr.

The Mu'tazila are a sect among the people of innovation, who differed from the Sunnis in the fundamentals of belief. They built their doctrine on denying Allah's attributes, the believers' vision of their Lord, Allah's elevatedness, and Allah's comprehensive decree that includes both the obedience and disobedience of His servants. They also ruled that the perpetrator of a grave sin would abide eternally in Hellfire.
