The Messenger of Allah said: "The Black Stone descended from the Paradise, and it was more white than milk, then it was blackened by the sins of the children of Adam."
قَالَ رَسُولُ اللَّهِ ﷺ نَزَلَ الْحَجَرُ الأَسْوَدُ مِنَ الْجَنَّةِ وَهُوَ أَشَدُّ بَيَاضًا مِنَ اللَّبَنِ فَسَوَّدَتْهُ خَطَايَا بَنِي آدَمَ قَالَ وَفِي الْبَابِ عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو وَأَبِي هُرَيْرَةَ
