This is hilarious. I have no idea what is going on but I have a theory. The beggar is non-Muslim, because if he was a Muslim, he’d be praying (at least I’d hope so). The beggar is trying to benefit from the generosity of Muslims, especially the ones who come to the Masjid for prayer. They would be the most generous. The first brother who comes late to the salah gives the beggar some money. The second brother does not and faces the punishment of being tripped by the beggar, which causes a domino effect to completely obliterate the entire line of brothers in prayer.
Is this staged? Possibly. Is this for real? Allah knows best.
I just think it’s funny. Hahaha!
