The Messenger of Allah said about the (Black) Stone: "By Allah! Allah will raise it on the Day of Resurrection with two eyes by which it sees and a tongue that it speaks with, testifying to whoever touched it in truth."
قَالَ رَسُولُ اللَّهِ ﷺ فِي الْحَجَرِ وَاللَّهِ لَيَبْعَثَنَّهُ اللَّهُ يَوْمَ الْقِيَامَةِ لَهُ عَيْنَانِ يُبْصِرُ بِهِمَا وَلِسَانٌ يَنْطِقُ بِهِ يَشْهَدُ عَلَى مَنِ اسْتَلَمَهُ بِحَقٍّ
