حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا الْمُغِيرَةُ، - يَعْنِي الْحِزَامِيَّ - عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ ‏"‏ لَمَّا خَلَقَ اللَّهُ الْخَلْقَ كَتَبَ فِي كِتَابِهِ فَهُوَ عِنْدَهُ فَوْقَ الْعَرْشِ إِنَّ رَحْمَتِي تَغْلِبُ غَضَبِي ‏"‏ ‏.‏
Translation
'Ala' reported on the authority of his father who reported on the authority of Abu Huraira that Allah's Messenger (ﷺ) said

If a believer were to know the punishment (in Hell) none would have the audacity to aspire for Paradise (but he would earnestly desire to be rescued from Hell), and if a non-believer were to know what is there with Allah as a mercy. none would have been disappointed in regard to Paradise.
