Why do Meccan surahs often focus on judgment and monotheism?

Meccan surahs in the Qur'an emphasize judgment and monotheism as central responses to the religious and social environment of early 7th-century Mecca.

Eschatological Judgment

The focus on the Day of Judgment (yawm al-din) served to warn the original audience of an impending cosmic reckoning. These passages emphasize that God’s verdict will be based solely on individual merit, challenging the prevailing tribal reliance on kinship for protection. By depicting the disintegration of the cosmos and the accountability of every soul, the text highlights the necessity of taqwa (fearful wariness of God). This focus also addressed social inequities, as the Qur'an links disbelief in the judgment to the mistreatment of vulnerable members of society, such as orphans and the poor.1

Monotheism and Polemics

The doctrine of monotheism—or tawhid—emerged as a direct challenge to the polytheistic practices of the Meccan Quraysh. Opponents were criticized for "associationism," the practice of relying on subordinate deities as intercessors rather than exclusively on Allah. Muhammad urged his listeners to abandon these traditional practices in favor of the original, aniconic worship of the one God, which he identified as the true legacy of Abraham.123
