وَاعْبُدُوا اللَّهَ وَلَا تُشْرِكُوا بِهِ شَيْئًا ۖ وَبِالْوَالِدَيْنِ إِحْسَانًا وَبِذِي الْقُرْبَىٰ وَالْيَتَامَىٰ وَالْمَسَاكِينِ وَالْجَارِ ذِي الْقُرْبَىٰ وَالْجَارِ الْجُنُبِ وَالصَّاحِبِ بِالْجَنبِ وَابْنِ السَّبِيلِ وَمَا مَلَكَتْ أَيْمَانُكُمْ

This comprehensive verse outlines the fundamental social ethics of Islam, beginning with the worship of Allah alone and extending to kind treatment of various categories of people. It establishes a hierarchy of social responsibilities, starting with parents and extending to relatives, vulnerable groups (orphans and the needy), neighbors (both close and distant), companions, travelers, and those under one's authority. This verse teaches that faith must be expressed through ethical treatment of all people, particularly those with whom we have relationships or who are vulnerable. It demonstrates that Islam is not merely about ritual worship but encompasses a complete ethical system for social interactions.
