The Prophet Shu'ayb is a man of wisdom and justice sent by Allah to guide the people of Madyan, who were involved in unjust practices such as cheating in trade and exploiting the weak. He preached to them the worship of Allah and integrity in business, calling for fairness, honesty, and piety. Despite his efforts, the majority of his people rejected his message, and Allah punished those who persisted in their disbelief and injustice.
