Is selling comic books that contain images of angels permissible or forbidden?

The basic principle for selling newspapers, magazines, books, and stories is permissibility, based on the generality of Allah's Almighty saying: "Allah has permitted trade and forbidden usury." However, if these aforementioned items contain forbidden elements, such as images of unveiled women, or alleged images of angels and messengers, or content that diminishes Islam, or encourages what is forbidden, or slanders people, or spreads rumors, then selling and trading them becomes forbidden. This is because when Allah forbids something, He also forbids its price. A Muslim should therefore safeguard their religion and purify their earnings.
