On the Day We will say to Hell, "Have you been filled?" and it will say, "Are there some more,"
Narrated Anas bin Malik:
The Prophet (sallallaahu alayhi wa sallam) said, "The Hell Fire will keep on saying: 'Are there anymore (people to come)?' Till the Lord of Power and Honor will put His Foot over it and then it will say, 'Qat! Qat! (sufficient! sufficient!) by Your Power and Honor. And its various sides will come close to each other (i.e., it will contract). "
[Sahih al-Bukhaari Hadith No. 6661]
