Musa al-Sadr was a very important religious leader from Lebanon. He helped many people and wanted peace. In 1978, he went to Libya and then he disappeared. Many people did not know what happened to him. Some people thought he was dead, but others thought he was still alive.

Many years later, a journalist found a photo of a dead body in Libya. The body looked like Musa al-Sadr. Scientists in England used a computer to check if the body was him. The computer said it was probably him, but not 100%. Some people took hair from the body to do a DNA test, but the hair was lost.

Some people still believe Musa al-Sadr is alive. His family and his followers do not believe the photo is him. Every year, people remember him and hope to find the truth. The mystery is not solved, and many people still have questions.
