Hadith 2734
Sayyiduna Ibn Abbas (may Allah be pleased with them both) narrates from the Noble Prophet (peace be upon him) that he said: "The Black Stone was one of the white jewels of Paradise; indeed, the sins of the polytheists have blackened it. On the Day of Resurrection, it will be raised up in the form of the mountain of Uhud. It will bear witness for every person among the people of the world who touched it or kissed it."
