Free mixing in Islam refers to the interaction between men and women who are not related by blood or marriage. The Islamic ruling on free mixing is a topic of debate among scholars, with some arguing that it is permissible as long as Islamic guidelines are followed, while others argue that it is forbidden.

Those who argue that free mixing is permissible state that it is allowed in certain contexts, such as in the workplace or in educational settings, as long as Islamic guidelines are followed, such as observing hijab and lowering the gaze. However, they also acknowledge that free mixing can lead to fitnah (temptation) and should be avoided if possible.

On the other hand, those who argue that free mixing is forbidden state that it goes against Islamic principles of modesty and can lead to sin and corruption. They argue that the Quran and Sunnah discourage and forbid such mixing, and cite verses that encourage men and women to lower their gaze and guard their modesty. They also point out that the Prophet Muhammad (peace be upon him) discouraged free mixing and intermingling of Muslim men and women.

In conclusion, the Islamic ruling on free mixing is a topic of debate among scholars, with some arguing that it is permissible in certain contexts as long as Islamic guidelines are followed, while others argue that it is forbidden and goes against Islamic principles of modesty.
