Anas bin Malik, may Allah be pleased with him, narrates that the Prophet, peace and blessings be upon him, said: "Hell will keep saying «هل من مزيد» 'Is there any more (to come)? Bring (them), put them in my belly,'" (Qaf: 30), until Allah, the Lord of Honor, will place His Foot in it. At that time, Hell will say «قط قط» "Enough, enough," and by Your honor and majesty (after that) one part of Hell will merge into another part. 1 Imam Tirmidhi says:
1- This hadith is Hasan Sahih Gharib through this chain,
2- In this chapter, there is also a narration from Abu Hurairah, may Allah be pleased with him. Benefit 1: That is, one part will cling to another part and become united.
