Silsilah Sahihah

It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: "Indeed, hot water will be poured over their (the people of Hell) heads, it will tear through the body until it reaches their stomachs, and whatever is inside the stomach will be expelled in such a way that it will flow out from their feet. This is «صهر» (melting) (which is mentioned in the Noble Qur'an), then they will be given the same form as they had before."
