Suleiman made his comments in the mountain village of Brih during a ceremony on reconciliation between the Druse and Christian community in the area that witnessed deadly sectarian violence during Lebanon's 1975-90 civil war.
"I appeal for the return to Lebanon and to withdraw from neighboring arenas to avoid future repercussions on Lebanon," said Suleiman, a critic of Hezbollah backing Syrian President Bashar Assad's forces.
Hezbollah, which openly joined the battles in Syria last year, is not likely to abide by Suleiman's call. Hezbollah leader Sheik Hassan Nasrallah has vowed to keep his fighters in Syria as long as needed to shore up Assad's struggle against Syria's rebels.
Suleiman's comments came a week before his six-year term ends.
