The Quranic concept of 'each group given a law and a way of life' is a cornerstone of Islamic theology, primarily articulated in Surah Al-Ma'idah, verse 48. It signifies that while all prophets preached the core message of monotheism (Tawheed), Allah in His wisdom prescribed specific laws (Shari'ah or Shir'ah) and a clear path (Minhaj) for each community, tailored to their time and circumstances. According to classical scholars such as Ibn Kathir, this diversity in legislation was a divine test to see which community would excel in good deeds. The advent of Islam with Prophet Muhammad ﷺ brought the final and universal Shari'ah, which abrogates and perfects the previous laws, with the Quran acting as a guardian over earlier revelations. This principle provides a framework for understanding the history of divine guidance and the universality of the final message of Islam.
