It was narrated from Anas bin Malik that the Messenger of Allah ﷺ said:
“This nation has been granted mercy (in the Hereafter) and its torment (in this world) is at the hands of one another. When the Day of Resurrection comes, each Muslim man will be given a man from among the idolaters and it will be said: ‘This is your ransom from the Fire.’”

حَدَّثَنَا جُبَارَةُ بْنُ الْمُغَلِّسِ، حَدَّثَنَا كَثِيرُ بْنُ سُلَيْمٍ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ قَالَ رَسُولُ اللَّهِ ﷺ " إِنَّ هَذِهِ أُمَّةٌ مَرْحُومَةٌ عَذَابُهَا بِأَيْدِيهَا فَإِذَا كَانَ يَوْمُ الْقِيَامَةِ دُفِعَ إِلَى كُلِّ رَجُلٍ مِنَ الْمُسْلِمِينَ رَجُلٌ مِنَ الْمُشْرِكِينَ فَيُقَالُ هَذَا فِدَاؤُكَ مِنَ النَّارِ " .
