Numerous studies have been made about the topic of Islamisation, where some see it as life, progress and reform, whereas others are convinced that it is nothing but destruction, violence, extremism and killing. Each of these two directions have their stated arguments and background that they rely on. This paper aims at establishing that Islam has the ability to manage the life of an individual and society on metaphysical and logical foundations, and based on clear human principles. The ambiguity in this article is regarding the purport of Islamisation as far as its meaning or its application. This study focuses on revealing the cases of Islamisation that the Ijtihad of Islamic scholars have established, through their experiences in their lives, and throughout history. According to our report, this can be summarised in the category of text, intellectuality and rationality, limited it from the aspect of conceptualisation and indication. There is also an emphasis on the benefits that come from Islamisation, based on this combination, like opening towards change, inviting unity, proximity, that intellectuality and rationality is the substance of religion, and so on. The approach this article used was analytical, with some descriptive explanations, and also relying on analysis generally common among Muslims.
