Musannaf Ibn Abi Shaybah

Hazrat Waleed bin Ubadah narrates from his father that during his final illness, he went to him and he said: I heard the Messenger of Allah, peace and blessings be upon him, say that Allah Almighty created the Pen first. Then He said to it, "Move." So the Pen moved and it wrote down all the events that would occur until the Day of Judgment.
