Ok I agree he kissed it once that's fine but why he did not destroyed it later like he destroyed other idols
The reason is due to the black stone
was not worshipped hence why it was not destroyed. Not to mention the black stone
does not have sculptured form that resemble something of a deity.
Idols by the way are erected
sculptures resembling Gods.
The Prophet (ﷺ) entered Mecca. There were three hundred and sixty idols around the Ka'ba. He began to thrust them with the stick that was in his hand saying:" Truth has come and falsehood has vanished. Lo! falsehood was destined to vanish" (xvii. 8). Truth has arrived, and falsehood can neither create anything from the beginning nor can It restore to life
One of the logical reason why black stone was
not worthy to be worshipped as an idol was due to its
physical appearance looking weak and not perfect. And
not being able to stand by itself among the
other idols around Ka'ba.
