Narrated Abu Huraira:
حَدَّثَنَا إِسْمَاعِيلُ ، حَدَّثَنِي مَالِكٌ ، عَنْ أَبِي الزِّنَادِ ، عَنِ الأَعْرَجِ ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " لَمَّا قَضَى اللَّهُ الْخَلْقَ كَتَبَ عِنْدَهُ فَوْقَ عَرْشِهِ، إِنَّ رَحْمَتِي سَبَقَتْ غَضَبِي " .
Allah's Messenger (ﷺ) said, "When Allah created the creations, He wrote with Him on His Throne: 'My Mercy has preceded My Anger."
