Is it permissible to dye animals, such as chicks, to attract customers in business?

Summary

Dyeing animals for business purposes or merely to satisfy desire is forbidden (haram). The act is regarded as cruelty and injustice toward the animal, since the chemicals in paint or colour spray may harm its health and can even cause its death. Although trade and promotion are generally permitted, they must not involve mistreating animals, as Islam requires kindness toward them.
