This research is motivated by the system of social rules implemented by pre-Islamic Arab society. These social rules trigger problems in terms of gender equality and tolerance between humans. Even at that time, it was very easy to find practices of violence and war. All the problems that occurred were completely inconsistent with Islamic teachings, because they included inhumane acts. Based on this problem, pre-Islamic Arab society was known as a jahiliyah society. However, in today's advanced era, problems are still found that are similar to the pre-Islamic Arab era. Based on these circumstances, this article aims to explain a number of extremism problems originating from the inhumane social rules of pre-Islamic Arab society in terms of the values of moderation and tolerance of Islamic teachings and the current reality.
