حَدَّثَنَا مُحَمَّدُ بْنُ عَمْرِو بْنِ عَبَّادِ بْنِ جَبَلَةَ بْنِ أَبِي رَوَّادٍ، حَدَّثَنَا حَرَمِيُّ بْنُ عُمَارَةَ، حَدَّثَنَا شَدَّادٌ أَبُو طَلْحَةَ الرَّاسِبِيُّ، عَنْ غَيْلاَنَ بْنِ جَرِيرٍ، عَنْ أَبِي بُرْدَةَ، عَنْ أَبِيهِ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏"‏ يَجِيءُ يَوْمَ الْقِيَامَةِ نَاسٌ مِنَ الْمُسْلِمِينَ بِذُنُوبٍ أَمْثَالِ الْجِبَالِ فَيَغْفِرُهَا اللَّهُ لَهُمْ وَيَضَعُهَا عَلَى الْيَهُودِ وَالنَّصَارَى ‏"‏ ‏.‏ فِيمَا أَحْسِبُ أَنَا ‏.‏ قَالَ أَبُو رَوْحٍ لاَ أَدْرِي مِمَّنِ الشَّكُّ ‏.‏ قَالَ أَبُو بُرْدَةَ فَحَدَّثْتُ بِهِ عُمَرَ بْنَ عَبْدِ الْعَزِيزِ فَقَالَ أَبُوكَ حَدَّثَكَ هَذَا عَنِ النَّبِيِّ صلى الله عليه وسلم قُلْتُ نَعَمْ ‏.‏

Abu Burda reported Allah's Messenger (PBUH) as saying: There would come people amongst the Muslims on the Day of Resurrection with as heavy sins as a mountain, and Allah would forgive them and He would place in their stead the Jews and the Christians. (As far as I think), Abu Raub said: I do not know as to who is in doubt. Abu Burda said: I narrated it to 'Umar b. 'Abd al-'Aziz, whereupon he said: Was it your father who narrated it to you from Allah's Apostle (PBUH)? I said: Yes. Translation Not Available
