The political domination that Muslims enjoyed in the later period produced a psychology of pride in them. They began considering themselves superior to others. This mentality caused them to use the terminologies of Dar ul-Islam (Abode of Islam) for the land they ruled, and Dar ul-Kufr (Abode of Disbelief) for the land ruled by other religious communities, though according to the Quran the whole world was equally Dar ul-Insan (Abode of Humankind). The definitions of Dar ul-Islam and Dar ul-Kufr constitute an innovation devised in later times. This attitude led Islam to be looked upon as only a collection of commandments and statutes.
