SAHIH MUSLIM ~
Abu Huraira reported Allah’s Messenger (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 animals 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 ninety nine 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 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 ” .Reference : Sahih Muslim 2752 c

Never ever belittle the mercy of your Master.. He has infinite levels of Mercy.. this Hadith is an evidence of how infinite is Allah’s mercy. Just one part of His Almighty’s Mercy is on this Earth and it’s just because of that one single part that a mother loves her child so much,a brother loves his sister and vice versa… It’s only because of that one part of Allah’s mercy that different relationships exist tied with the strong bond of love…. Then how can Allah’s mercy be belittled. Trust your Rabb .. and have patience at times of difficulties.
