Hadith 39, 40 Hadith Qudsi
On the authority of Abu Sa'id al-Khudri (may Allah be pleased with him), who said that the Messenger of Allah (ﷺ) said:
Paradise and Hell-fire disputed together, and Hell-fire said: In me are the mighty and the haughty. Paradise said: In me are the weak and the poor. So Allah judged between them, [saying]: You are Paradise, My mercy; through you I show mercy to those I wish. And you are Hell-fire, My punishment; through you I punish those I wish, and it is incumbent upon Me that each of you shall have its fill.

It was related by Muslim (also by al-Bukhari and at-Tirmidhi).
عَنْ أَبي سَعيدٍ الْخُدْريّ رَضِيَ اللهُ عَنْهُ عَن النَّبِيّ صَلَّى الله عَلَيْهِ وَ سَلَّمَ قَالَ : احْتَجَّتِ الجَنَّةُ والنَّارُ فَقَالتِ النَّارُ : فِيَّ الجَبَّارونَ والمُتكَبَّرونَ  وَقَالتِ الجَنَّةُ : فِيّ ضُعَفاءُ النَّاسِ ومساكينُهُمْ  فَقَضَى اللهُ بَيْنَهُما : إِنَّكِ الجَنَّةُ رَحْمَتِي أَرْحَمُ بِكِ مَنْ أَشاءُ، وإنكِ النارُ عذابي ، أُعَذِبُ بِكِ من أشاءُ ،  وَلِكلَيْكُما عَلَيَّ مِلْؤُها
