إِنَّ اللَّهَ لَا يُضِيعُ أَجْرَ الْمُحْسِنِينَ

This verse reassures believers that their good deeds will never go unrewarded by Allah. It serves as a motivation for believers to continue doing good, even when they don't see immediate results or face challenges. The term 'Muhsineen' (those who do good) refers to those who perform actions with excellence and sincerity, seeking Allah's pleasure.
