'Ala' reported on the authority of his father who reported on the authority of Abu Huraira that Allah's Messenger (ﷺ) said:

4) باب فِي سَعَةِ رَحْمَةِ اللَّهِ تَعَالَى وَأَنَّهَا سَبَقَتْ غَضَبَهُ ‏‏

حَدَّثَنَا يَحْيَى بْنُ أَيُّوبَ، وَقُتَيْبَةُ، وَابْنُ، حُجْرٍ جَمِيعًا عَنْ إِسْمَاعِيلَ بْنِ جَعْفَرٍ، قَالَ ابْنُ أَيُّوبَ حَدَّثَنَا إِسْمَاعِيلُ، أَخْبَرَنِي الْعَلاَءُ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏‏ ‏.‏ "‏ لَوْ يَعْلَمُ الْمُؤْمِنُ مَا عِنْدَ اللَّهِ مِنَ الْعُقُوبَةِ مَا طَمِعَ بِجَنَّتِهِ أَحَدٌ وَلَوْ يَعْلَمُ الْكَافِرُ مَا عِنْدَ اللَّهِ مِنَ الرَّحْمَةِ مَا قَنِطَ مِنْ جَنَّتِهِ أَحَدٌ ‏"
