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.
قَالَ رَسُولُ اللَّهِ ﷺ إِنَّ لِلَّهِ مِائَةَ رَحْمَةٍ فَمِنْهَا رَحْمَةٌ بِهَا يَتَرَاحَمُ الْخَلْقُ بَيْنَهُمْ وَتِسْعَةٌ وَتِسْعُونَ لِيَوْمِ الْقِيَامَةِ
