Since the Quran claims that Allah sent prophets all over the world, why does it mention only Biblical prophets? Why doesn’t it mention any prophet sent to an undiscovered land like Japan?

 The Quran, the holy book of Islam, acknowledges the sending of prophets to various nations and communities. While many of the prophets mentioned in the Quran are shared with the Bible, Islam teaches that there were numerous prophets sent to different peoples throughout history. However, the Quran focuses on specific regions and communities that were historically significant in the Arabian context, and it highlights the messages and struggles of prophets within those regions.

Here are a few key points to consider:

1. **Universal Message:** Islam teaches that the message of monotheism and submission to God (Allah) is universal and has been delivered to all nations at different times through various prophets. The Quran states, "And We certainly sent into every nation a messenger, [saying], 'Worship Allah and avoid Taghut (false gods)'" (Quran 16:36).

2. **Focus on Arabian Prophets:** The Quran emphasizes the stories of certain prophets who were central to the Arabian Peninsula and the immediate surroundings. This includes prophets like Adam, Noah, Abraham, Moses, and Jesus, among others.

3. **Guidance for Humanity:** While the Quran highlights the stories of specific prophets, it does not necessarily provide an exhaustive list of all prophets or cover every corner of the world. Instead, it emphasizes the guidance and lessons derived from the stories to serve as a source of moral, spiritual, and ethical guidance for humanity.

4. **Limited Historical Context:** The Quran was revealed in a specific historical and cultural context to the Prophet Muhammad in 7th-century Arabia. The focus on certain prophets and regions in the Quran is consistent with the needs and understanding of the audience to whom it was initially revealed.

It's important to note that the absence of specific mention of prophets in certain regions does not negate the belief in the universality of prophethood in Islam. Muslims believe in the concept of "Rusul," which refers to messengers sent by God to convey His guidance to different communities throughout history. The Quran encourages believers to reflect on the diversity of prophets and the unity of their essential message across time and place.
