Musnad Abu Ya'la al-Mawsili 160:103

And with his chain of narration, that the Messenger of Allah (may Allah bless him and grant him peace) said: "The sun does not rise nor set upon a day better than the day of Friday. There is no creature except that it is afraid of the day of Friday, except for these two heavy ones: the Jinn and mankind. At every door of the doors of the mosque are two angels writing down the first, then the first. It is like a man who offered a camel, and like a man who offered a cow, and like a man who offered a sheep, and like a man who offered a bird, and like a man who offered an egg. So when the Imam sits, the scrolls are folded."
