It is narrated from Hazrat Anas bin Malik (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: (Some people from my Ummah will be admitted into Hell; when they are burnt and become like coal, they will be admitted into Paradise.) The people of Paradise will ask: Who are these people? It will be said to them: These are the people of Hell.
