Quran and hadith

Was the Quran preserved?

How do we know the Quran was not changed?

Reviewed by Bayan

Simple answer

The Quran says that God Himself sent down the Reminder and will guard it, and it describes the Quran as a revelation that falsehood cannot reach from any angle. 15:941:42

Other verses say that its safe collection, recitation, and clarification are with God, so these texts provide the Quran's faith-based foundation for its preservation. 75:1775:1875:19
