Sahih Muslim 2846b states:
Abu Huraira reported Allah’s Messenger (ﷺ) as saying:
The Hell and the Paradise fell into dispute and the Hell said: I have been distinguished by the proud and the haughty. And the Paradise said: What is the matter with me that the meek and the humble amongst people and the downtrodden and the simple enter me? Thereupon Allah said to the Paradise: You are (the means) of My Mercy whereby I show mercy to those of My servants whom I wish, and He said to the Hell: You are (the means) of punishment whereby I punish those of My servants whom l wish. Both of you will be full. The Hell will riot be filled up until Allah puts down His foot in it. The Hell would say: Enough, enough, enough, and at that time it will be filled up, all its parts integrated together.
