Abu Huraira reported Allah's Apostle (ﷺ) as saying:
وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ ، حَدَّثَنَا أَحْمَدُ بْنُ إِسْحَاقَ ، حَدَّثَنَا وُهَيْبٌ ، حَدَّثَنَا عَبْدُ، اللَّهِ بْنُ طَاوُسٍ عَنْ أَبِيهِ ، عَنْ أَبِي هُرَيْرَةَ ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " فُتِحَ الْيَوْمَ مِنْ رَدْمِ يَأْجُوجَ وَمَأْجُوجَ مِثْلُ هَذِهِ " . وَعَقَدَ وُهَيْبٌ بِيَدِهِ تِسْعِينَ .
