First of all, they don't even have the courage to go to a land war. Second, just look at them, it's obvious they're not in any kind of a combat situation. Third, they're not in a battle at all, they're inside a mosque. And fourth, even if they were, they should still take off their shoes to pray. Allah said to Moses in the "sacred" valley, (إخلع نعليك إنك في الوادي "المقدس" طوى) So who does this Zionist, Mohammed bin Salman,or anyone else, think they are, walking into a mosque, which is a sacred place, with their shoes on?
