Islamic finance has engaged index investing directly, and the result is a mature set of rules. The core permission is trade (2:275): owning a share of a productive business and sharing its risk is halal in principle. The conditions are screening (excluding alcohol, gambling, pork, conventional interest-based finance, and adult entertainment), purification (donating the proportion of impure income, typically small interest earnings), and structure (avoiding margin interest and most derivatives). Halal and Shariah-screened index funds exist precisely to make compliance easy, supervised by scholarly boards. Beyond the mechanics, Islam treats wealth as an amanah (trust) — the believer owns nothing absolutely and is questioned about how every dirham was earned and deployed. Zakat (typically 2.5% of qualifying wealth annually) functions as a spiritual reminder that the portfolio serves God's purposes, not the reverse. 'Seeking of the bounty of Allah' through travel and trade is even commanded in the Quran (73:20), as long as prayer and remembrance are not crowded out.
