What is the difference between Meccan and Medinan surahs?

In Islamic tradition, the Qur'an is categorized into Meccan (Makkiyyah) and Medinan (Madaniyyah) surahs, with the watershed between them being the Prophet Muhammad’s migration from Mecca to Medina in 622 CE.12

Traditional Distinctions

• Meccan Surahs: Traditionally associated with Muhammad's earlier ministry in Mecca, these texts often focus on eschatology, the oneness of God (monotheism), and the Day of Judgment. They frequently feature shorter verses and are characterized by a tone of warning and moral exhortation.312
• Medinan Surahs: Associated with the period following the migration to Medina, these surahs often contain detailed legal regulations and address the needs of the growing Muslim community (ummah). They reflect a shift toward communal organization, the critique of other religious traditions, and the expectation of militant "striving" for God.31

Scholarly Perspectives

While traditional classification links these labels to the location of revelation, modern critical scholarship often questions the validity of these rigid divisions, noting that the text's composition is complex and may not align perfectly with a linear historical chronology.12
