What is the interpretation of seeing a black body obscuring the Kaaba during Tawaf, with the answer being that it is Iblis?

The devils may appear to people and be seen by them. The jinn can take the forms of humans and animals. Some Companions saw individuals from the jinn and spoke with them. However, seeing devils does not mean that what they say is true, because they are liars and deceivers. Therefore, it is not far-fetched for some to see devils in forms they assume, but this does not necessitate believing them. Whoever sees them should seek refuge with Allah from their evil, occupy themselves with the remembrance of Allah and obedience to Him, and turn away from thinking about their affairs.
