Hadith – Sahih Bukhari 6:373, Narrated Abu Huraira
The Prophet said, “Paradise and the Fire (Hell) argued, and the Fire (Hell) said, ‘I have been given the privilege of receiving the arrogant and the tyrants.’ Paradise said, ‘What is the matter with me? Why do only the weak and the humble among the people enter me?’ On that, Allah said to Paradise, ‘You are My Mercy which I bestow on whoever I wish of my servants.’ Then Allah said to the (Hell) Fire, ‘You are my (means of) punishment by which I punish whoever I wish of my slaves. And each of you will have its fill.’ As for the Fire (Hell), it will not be filled till Allah puts His Foot over it whereupon it will say, ‘Qati! Qati!’ At that time it will be filled, and its different parts will come closer to each other; and Allah will not wrong any of His created beings. As regards Paradise, Allah will create a new creation to fill it with.”
