Sahih al-Bukhari
Beginning of Creation
Chapter: The Statement of Allah Taa'la: "And He it is Who originates the creation; then will repeat it and this is easier for Him..."
Narrated 'Umar:
One day the Prophet (ﷺ) stood up amongst us for a long period and informed us about the beginning of creation (and talked about everything in detail) till he mentioned how the people of Paradise will enter their places and the people of Hell will enter their places. Some remembered what he had said, and some forgot it.
