The Quran, the holy book of Islam, does not provide a specific number for the planets in our solar system. The Quran was revealed over 1,400 years ago and primarily focuses on providing guidance on matters of faith, spirituality, morality, and human conduct. It does mention celestial bodies, including the sun, the moon, and stars, but it does not enumerate or describe the planets as we understand them in modern astronomy.
It is worth noting that scientific understanding of the solar system and planets has developed significantly since the Quran was revealed. The concept of planets as understood by modern astronomy was not prevalent during the time of its revelation, and therefore, the Quran does not provide explicit details regarding the specific number or nature of planets in our solar system.
