أحسن الله إليكم Ustaadh, There’s a trend where if you receive a certain video, you have to buy food for the person who sent the video. Is this permissible?

Take it as a rule: it is not allowed in Islam to force someone to pay anything, or even to embarrass them or make them feel shy and shamed just to get money from them. This is not allowed in Islam. Even for a father with his own children, this is not permitted.
