Sahih Sahl bin Sa’d (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings of Allah be upon him) said: On the Day of Resurrection, people will be gathered on a white, reddish-tinged plain like a loaf of bread, on which no mark of anyone will remain (that is, there will be no buildings such as houses or minarets, it will become a smooth, level plain).
