bleu,, why would he face problems?! As far I know,,it wont be too difficult to pass the Saudi Border if you possess a proper transit visa (if applicable to you).
Saudi border has just started to register finger prints of everyone entering the border which is irritating but you may pass through after that.

khalil,, i dont think you would find someone to go all the way to lebanon at that exact time here on QL. 5% chance.
