The study compared how well Islamic mutual funds perform against regular mutual funds by looking at equity and fixed income funds. The goal was to see which type of fund did better. Islamic mutual funds are designed to follow Islamic principles, while regular mutual funds don't have these restrictions. The researchers wanted to see if there was a difference in performance between the two types of funds. They found that Islamic mutual funds performed similarly to regular mutual funds in terms of returns. This means that both types of funds can be good options for investors looking to make money while following different investment principles.
