Human diversity is a social reality explicitly acknowledged in the Qur'an. Nevertheless, contemporary da'wah practices in certain contexts continue to exhibit exclusive tendencies that may contribute to social and religious tensions. This article aims to examine the concept of inclusive da'wah in the Qur'an through an interpretive analysis of verses concerning human diversity. The study employs a qualitative research design using a thematic (maudhu'i) tafsir approach. Primary data consist of Qur'anic verses related to human plurality, while secondary data are derived from classical and contemporary tafsir literature. The analysis focuses on exploring the meanings, contexts, and contemporary relevance of these verses within the framework of Islamic preaching. The findings reveal that the Qur'an views human diversity as a divine ordinance (sunnatullah) intended to foster mutual understanding, cooperation, and harmonious coexistence among people. The principles of inclusive da'wah derived from the Qur'an include the recognition of diversity, respect for human dignity, constructive dialogue, and the delivery of religious messages with wisdom and compassion. The study further demonstrates that Qur'anic da'wah is not oriented toward coercion or religious compulsion but rather toward moral and social transformation that appreciates and accommodates the pluralistic nature of human society. These findings contribute to the development of a Qur'anic framework for inclusive da'wah that is relevant to contemporary multicultural societies and the promotion of religious moderation
