What is it that is in Paradise and is also found in the Kaaba?

The pure Prophetic Sunnah does not mention anything in the Kaaba being from Paradise except for two things:

1. The Black Stone: It descended from Paradise and was whiter than milk, but the sins of the children of Adam turned it black. 2. Maqam Ibrahim (Station of Abraham): It is stated in the Hadith that it and the Corner (the Black Stone) are two rubies from the rubies of Paradise, whose light Allah obscured. Were it not for that, they would illuminate everything between the East and the West. This Hadith was authenticated by An-Nawawi, Ibn Taymiyyah, and Al-Albani.
