Sahih Muslim Book - 49, Hadith - 6974

حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ نُمَيْرٍ حَدَّثَنَا أَبِى حَدَّثَنَا عَبْدُ الْمَلِكِ عَنْ عَطَاءٍ عَنْ أَبِى هُرَيْرَةَ عَنِ النَّبِىِّ -صلى الله عليه وسلم- 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 ».

It was narrated from Abu Hurairah that the Prophet (s.a.w) said: "Allah has one hundred (parts of) mercy, of which He sent one part down among jinn, humans, animals and insects, because of which they show compassion and kindness to one another, and a wild animal shows compassion to its young. And Allah has kept back ninety-nine parts of mercy by which He will show mercy to His slaves on the Day of Resurrection."
