Al-Ukhdood, or the "Ditch," is a historical event mentioned in the Quran, specifically in Surah Al-Burooj. It refers to a story about a group of believers who were persecuted by a tyrannical king. The king ordered a large ditch to be dug and filled with fire, where he would throw those who refused to renounce their faith. The story emphasizes themes of faith, sacrifice, and divine justice. It serves as a reminder of the struggles faced by believers throughout history, illustrating the consequences of standing firm in one's beliefs against oppression. The tale is often associated with the People of the Ditch and their unwavering commitment to their faith.
