The recent literature on Islamic economics hardly makes use of mathematics even for expositional purposes. Mathematics is a language. It keeps argument and logic straight.

For instance, the need is to show the impact and effects of Islamic principles on allocation of resources, income distribution, externalities and so on using mathematics.
