Musnad Ahmad Hadith 14491

It is narrated from Jabir (may Allah be pleased with him) that the Prophet (ﷺ) said: When the people of Paradise and the people of Hell will be distinguished, and the people of Paradise will enter Paradise and the people of Hell will enter Hell, then the noble Prophets will stand and intercede. They will be told: Go and bring out from Hell whomever you recognize. Thus, they will bring them out, and at that time their faces will have been burnt. Then they will be dipped into the River of Life, and when they come out from there, all their darkness will fall off at the bank of the river, and they will come out shining like cucumbers. After that, the noble Prophet (ﷺ) will intercede again. They will be told: Go and bring out from Hell anyone in whose heart you find faith equal to a qirat. Thus, they will bring out many people. Then they will intercede again, and they will be told: Go and bring out from Hell anyone in whose heart you find faith equal to a mustard seed. Thus, they will bring out many people. After that, Allah will say: Now I, with My knowledge and grace, will bring people out of Hell. Thus, a number double or triple the previous ones will be brought out of Hell, and it will be written on their necks that these are the slaves freed by Allah. Then, when they enter Paradise, they will be called "the people of Hell."
