Sahih Muslim 2846 a
Abu Huraira reported Allah's Messenger (ﷺ) as say- ing:
There was a dispute between the Hell and the Paradise and it (the Hell) said: The haughty and the proud would find abode in me. And the Paradise said: The meek and the humble would find their abode in me. Thereupon Allah, the Exalted and Glorious, (addressing the Hell) said: You are (the means) of My punishment by which I punish those of My servants whom I wish. (And addressing the Paradise) He said: You are only My Mercy by means of which 1 shall show mercy to those whom I wish, but each one of you would be full.
حَدَّثَنَا ابْنُ أَبِي عُمَرَ، حَدَّثَنَا سُفْيَانُ، عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ،
 قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏
"‏ احْتَجَّتِ النَّارُ وَالْجَنَّةُ فَقَالَتْ هَذِهِ يَدْخُلُنِي
 الْجَبَّارُونَ وَالْمُتَكَبِّرُونَ ‏.‏ وَقَالَتْ هَذِهِ يَدْخُلُنِي الضُّعَفَاءُ وَالْمَسَاكِينُ فَقَالَ اللَّهُ عَزَّ وَجَلَّ لِهَذِهِ
 أَنْتِ عَذَابِي أُعَذِّبُ بِكِ مَنْ أَشَاءُ - وَرُبَّمَا قَالَ أُصِيبُ بِكِ مَنْ أَشَاءُ - وَقَالَ لِهَذِهِ أَنْتِ
 رَحْمَتِي أَرْحَمُ بِكِ مَنْ أَشَاءُ وَلِكُلِّ وَاحِدَةٍ مِنْكُمَا مِلْؤُهَا ‏"‏ ‏.‏
