Sahih Muslim
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا أَبُو أُسَامَةَ، عَنْ طَلْحَةَ بْنِ يَحْيَى، عَنْ أَبِي، بُرْدَةَ عَنْ أَبِي مُوسَى، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " إِذَا كَانَ يَوْمُ الْقِيَامَةِ دَفَعَ اللَّهُ عَزَّ وَجَلَّ إِلَى كُلِّ مُسْلِمٍ يَهُودِيًّا أَوْ نَصْرَانِيًّا فَيَقُولُ هَذَا فَكَاكُكَ مِنَ النَّارِ " .
Abu Musa' reported that Allah's Messenger (ﷺ) said: When it will be the Day of Resurrection Allah would deliver to every Muslim a Jew or a Christian and say: That is your rescue from Hell-Fire.
