Musnad Abu Ya'la al-Mawsili 155:85

Abu Khaythama narrated to us, Ibn Idris narrated to us, Muhammad ibn ‘Amr narrated to us, from Abu Salamah, from Abu Hurayrah, who said: The Messenger of Allah (may Allah bless him and grant him peace) said: "The best day upon which the sun has risen is Friday. On it, Adam was created, on it he was entered into Paradise, and on it he was descended from it."
