Abu Huraira reported Messenger of Allah ﷺ as saying: There are one hundred (parts of) mercy for Allah and He has sent down out of these one part of mercy upon the jinn and human beings and the insects and it is because of this (one part) that they love one another, show kindness to one another and even the beast treats its young one with affection, and Allah has reserved ninetynine parts of mercy with which He would treat His servants on the Day of Resurrection.

حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ نُمَيْرٍ، حَدَّثَنَا أَبِي، حَدَّثَنَا عَبْدُ الْمَلِكِ، عَنْ عَطَاءٍ، عَنْ
أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ ﷺ قَالَ
" إِنَّ لِلَّهِ مِائَةَ رَحْمَةٍ أَنْزَلَ مِنْهَا رَحْمَةً
وَاحِدَةً بَيْنَ الْجِنِّ وَالإِنْسِ وَالْبَهَائِمِ وَالْهَوَامِّ فَبِهَا يَتَعَاطَفُونَ وَبِهَا يَتَرَاحَمُونَ وَبِهَا تَعْطِفُ
الْوَحْشُ عَلَى وَلَدِهَا وَأَخَّرَ اللَّهُ تِسْعًا وَتِسْعِينَ رَحْمَةً يَرْحَمُ بِهَا عِبَادَهُ يَوْمَ الْقِيَامَةِ " .
