Perhaps “Retired Libyan army General and current advisor to the UN-proposed government’s Defense Minister, Sulaiman Al-Abedi” has info:
“I was told of many secrets about Gaddafi’s regime, including the mystery of the disappearance of the Shiite Lebanese leader, Musa al-Sadr, and the officer Omer Al-Mahishi, who led a coup against Gaddafi in the early 1970s.”

Sadr’s ecumenism was viewed with alarm and anger among certain conservative Shia clerical circles in Lebanon. And even more so among pro-Khomeini clerics in Iran and specifically by Ayatollah Mohammed Beheshti, who was widely regarded as the second most powerful figure in Iran. “Is al-Sadr a Muslim or is he a Christian? Or maybe al-Sadr is a Jew?” Ayatollah Beheshti was reported to have asked a meeting of clerics in Teheran in July of 1978.
Shortly thereafter Beheshti reportedly asked Libya’s leader Moammar Gadaffi to invite Musa Sadr to Libya “for consultations.”
