Is it permissible to draw for products displayed online, and then sell them to the buyer for a specific amount placed as a product link on websites?

The question contained two matters:

First: Regarding the ruling on drawing on goods. If the drawing is of inanimate objects (such as a tree or the sea), there is no harm in it. However, if it is of animate beings, and the image is incomplete (such as a headless one), then some scholars see no harm in it. As for a complete image, the matter is more severe, and scholars have differed regarding its ruling, between permissibility and prohibition. Piety dictates limiting oneself to drawing that which has no soul, while ensuring the permissibility of the good itself.

Second: Regarding promoting goods via social media. There is no harm in this if the good is permissible and the promotion does not involve deception or fraud.
