What is the strongest opinion among jurists regarding the ruling on droppings that soil clothes or the body, the source of which is unknown? Are they ritually impure (najis) or pure (tahir), and why?

There are two scholarly opinions regarding this issue:

1. The ruling of impurity, because the default status of animal droppings is impurity. 2. The ruling of purity, which is the more correct view, because the default status of substances is purity.

Sheikh al-Islam Ibn Taymiyyah supports the second opinion, emphasizing that the claim of impurity as the default status for animal droppings is not based on a text or a consensus.
