Abstract
A nation state is a type of state that joins the political entity of a state to the cultural entity of a nation, from which it aims to derive its political legitimacy to rule and potentially its status as a sovereign state. A state is specifically a political and geopolitical entity, whilst a nation is a cultural and ethnic one. The term "nation state" implies that the two coincide, in that a state has chosen to adopt and endorse a specific cultural group as associated with it. On the other hand the conception of a state in Islam is that of a commonwealth of all the Muslims living as one community under the guidance and direction of a supreme executive head. Islamic state is a state in which every Muslim has a right to live his life according to the principles of the Quran and Sunnah. Pakistan is a relatively young experimental amalgamation of a ―Nation State‖ and an ―Islamic State‖. This article is an attempt to study the pros and cons of this experiment. She was a unique endeavor to show the world that Muslims of the South Asia of the twentieth century could run a Welfare Islamic State on the principles of Quran and Sunnah. As a nation of twenty million Muslims, Pakistan has achieved a lot of success and crossed several milestones. In this journey she has had to face a lot of obstacles which have slowed down its progress in many walks of life.
