What is the ruling on displaying a product – with pictures and specifications – as an advertisement to gauge market interest and determine the extent of public demand for it, without possessing it or intending to sell it?

Placing a product for sale that is contrary to reality, where the advertisement involves falsehood and harm to the shopper. The solution is to advertise the product without giving the impression that it is for sale, but merely for questioning and surveying opinion regarding consumer need for it and the suitability of its price.
