The Quran is a book of guidance. One of the principles of life has been stated in Chapter 92 of the Quran in these words: “Indeed, your efforts are diverse.” (92:4)
This means that according to the creation plan of God, there is no uniformity between people. Every person or group thinks along different lines. Along with this, everyone enjoys complete freedom in this world. On account of this nature of existence, it inevitably happens that various fields of human activity are formed.
Now the question is how to manage the diversity of human activities? If a particular group were given monopoly over something, then an unending war would begin in the world; there would no longer be peace, which is essential for all kinds of development.
Diversity exists in both religious and secular domains. In both fields, the workable formula is for people to live together with each other in the spirit of coordination; no one should confront with another but work peacefully.
