Abu Hurairah, may Allah be pleased with him, said:“The Messenger of Allah recited this Ayah: ‘That Day it will declare its information.’ He said: “Do you know what its information is?” They said: “Allah and His Messenger know better.” He said: “That it testifies about what every male or female slave (of Allah) did upon its surface. It says: ‘He did this and that on this day.’ This is its information.”
