Musa al-Sadr
Abi-Nader was repeatedly abducted, but was released on intervention of various politicians repeatedly. Together with the Imam Musa al-Sadr, he was committed to an understanding of both religions in Lebanon. During the military clashes between the Lebanese Forces (LF) and the regular Lebanese army, he campaigned with his life for fire breaks. He was also one of the principal representatives of the Lebanese Society for preservation of Francophonie in Lebanon.
