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." (Using translation from Tirmidhī 961)   

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ «لَيَبْعَثَنَّ اللَّهُ الْحَجَرَ يَوْمَ الْقِيَامَةِ وَلَهُ عَيْنَانِ يُبْصِرُ بِهِمَا وَلِسَانٌ يَنْطِقُ بِهِ يَشْهَدُ عَلَى مَنِ اسْتَلَمَهُ بِحَقٍّ» قَالَ سُلَيْمَانُ «لِمَنِ اسْتَلَمَهُ»
