What cannot be sold
Eight things are blocked at listing time. Everything else is declared, not banned — sellers declare zabiha status, alcohol content in cosmetics, ingredients, and condition. Buyers filter. This asymmetry is deliberate.
—Alcohol
—Pork and non-halal meat
—Gambling and lottery
—Interest-based finance (conventional loans, credit cards, conventional insurance — takaful is explicitly welcome)
—Dating and matchmaking
—Musical instruments
—Animals and pets
—Crypto and NFTs (blocked for fraud protection, not as a religious ruling)
