Qur’anic Guidance in Shariah-Based Business Ethics: How Halal Practices, Honest Dealings, and Kept Promises Shape Customer Satisfaction

Abstract

This study examines how Qur’anic and Shariah-based business principles directly influence the way customers evaluate and trust the businesses they interact with. The purpose is to show that practices such as offering halal and lawful products, avoiding any form of deception, and consistently fulfilling promises are not only religious obligations but also powerful drivers of customer satisfaction. To explore this connection, data were collected from 300 customers in Lahore, focusing on how these ethical practices shape their overall experience with local businesses. The results reveal that customers feel significantly more satisfied when they know a business follows halal standards, maintains transparency, and delivers exactly what it commits to. These behaviors build trust, reduce uncertainty, and strengthen long-term customer relationships. The originality of this work lies in presenting a simple, business-oriented model that links Qur’anic guidance with modern customer expectations. Rather than treating religious ethics as separate from business, this study shows how Shariah principles naturally support ethical service, customer comfort, and sustainable business success.
