Hadith Qudsi 1

On the authority of Abu Hurayrah, who said that the Messenger of Allah ﷺ said:

When Allah decreed the Creation He pledged Himself by writing in His book which is laid down with Him: My mercy prevails over my wrath.

It was related by Muslim (also by al-Bukhari, an-Nasa'i and Ibn Majah).

عَنْ أَبِي هُرَيْرَةَ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: " لَمَّا قَضَى اللَّهُ الْخَلْقَ، كَتَبَ فِي كِتَابِهِ عَلَى نَفْسِهِ، فَهُوَ مَوْضُوعٌ عِنْدَهُ: إِنَّ رَحْمَتِي تَغْلِبُ غَضَبِي" رواه مسلم (وكذلك البخاري والنسائي وابن ماجه)
