Sahih al-Bukhari
Oneness, Uniqueness of Allah (Tawheed) — Hadith #7404
لَمَّا خَلَقَ اللَّهُ الْخَلْقَ كَتَبَ فِي كِتَابِهِ ـ هُوَ يَكْتُبُ عَلَى نَفْسِهِ، وَهْوَ وَضْعٌ عِنْدَهُ عَلَى الْعَرْشِ ـ إِنَّ رَحْمَتِي تَغْلِبُ غَضَبِي "
The chain (isnad) appears to be missing from this record. Under review.
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.'”
لَمَّا خَلَقَ اللَّهُ الْخَلْقَ كَتَبَ فِي كِتَابِهِ ـ هُوَ يَكْتُبُ عَلَى نَفْسِهِ، وَهْوَ وَضْعٌ عِنْدَهُ عَلَى الْعَرْشِ ـ إِنَّ رَحْمَتِي تَغْلِبُ غَضَبِي ”
