Salman Farisi reported Messenger of Allah ﷺ as saying: Verily, there are one hundred (parts of) mercy for Allah, and it is one part of this mercy by virtue of which there is mutual love between the people and ninety-nine reserved for the Day of Resurrection.

حَدَّثَنِي الْحَكَمُ بْنُ مُوسَى، حَدَّثَنَا مُعَاذُ بْنُ مُعَاذٍ، حَدَّثَنَا سُلَيْمَانُ التَّيْمِيُّ، حَدَّثَنَا أَبُو
عُثْمَانَ النَّهْدِيُّ عَنْ سَلْمَانَ الْفَارِسِيِّ، قَالَ قَالَ رَسُولُ اللَّهِ ﷺ
" إِنَّ لِلَّهِ
مِائَةَ رَحْمَةٍ فَمِنْهَا رَحْمَةٌ بِهَا يَتَرَاحَمُ الْخَلْقُ بَيْنَهُمْ وَتِسْعَةٌ وَتِسْعُونَ لِيَوْمِ الْقِيَامَةِ " .
