Sahih al-Bukhari · Book 97: Oneness, Uniqueness of Allah (Tawheed) · “…And Allah warns you against Himself…”
Narrated Abu Huraira:
حَدَّثَنَا عَبْدَانُ ، عَنْ أَبِي حَمْزَةَ ، عَنِ الأَعْمَشِ ، عَنْ أَبِي صَالِحٍ ، عَنْ أَبِي هُرَيْرَةَ ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " لَمَّا خَلَقَ اللَّهُ الْخَلْقَ كَتَبَ فِي كِتَابِهِ ـ هُوَ يَكْتُبُ عَلَى نَفْسِهِ، وَهْوَ وَضْعٌ عِنْدَهُ عَلَى الْعَرْشِ ـ إِنَّ رَحْمَتِي تَغْلِبُ غَضَبِي " .
The Prophet (ﷺ) said, "When Allah created the Creation, He wrote in His Book--and He wrote (that) about Himself, and it is placed with Him on the Throne--'Verily My Mercy overcomes My Anger.'"
