Compiled by Imam Muhammad al-Bukhari
حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا يَعْقُوبُ بْنُ عَبْدِ الرَّحْمَنِ، عَنْ عَمْرِو بْنِ أَبِي عَمْرٍو، عَنْ سَعِيدِ بْنِ أَبِي سَعِيدٍ الْمَقْبُرِيِّ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ قَالَ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ " إِنَّ اللَّهَ خَلَقَ الرَّحْمَةَ يَوْمَ خَلَقَهَا مِائَةَ رَحْمَةٍ، فَأَمْسَكَ عِنْدَهُ تِسْعًا وَتِسْعِينَ رَحْمَةً، وَأَرْسَلَ فِي خَلْقِهِ كُلِّهِمْ رَحْمَةً وَاحِدَةً، فَلَوْ يَعْلَمُ الْكَافِرُ بِكُلِّ الَّذِي عِنْدَ اللَّهِ مِنَ الرَّحْمَةِ لَمْ يَيْأَسْ مِنَ الْجَنَّةِ، وَلَوْ يَعْلَمُ الْمُؤْمِنُ بِكُلِّ الَّذِي عِنْدَ اللَّهِ مِنَ الْعَذَابِ لَمْ يَأْمَنْ مِنَ النَّارِ ".
I heard Allah's Messenger (ﷺ) saying, Verily Allah created Mercy. The day He created it, He made it into one hundred parts. He withheld with Him ninety-nine parts, and sent its one part to all His creatures. Had the non-believer known of all the Mercy which is in the Hands of Allah, he would not lose hope of entering Paradise, and had the believer known of all the punishment which is present with Allah, he would not consider himself safe from the Hell-Fire."
