Musnad Abu Ya'la al-Mawsili 42:71

Ahmad ibn Isa narrated to us, Abdullah ibn Wahb narrated to us, and Haywah ibn Shurayh informed me, from Bashir al-Khawlani, that al-Walid ibn Qays narrated to him, that Abu Sa’id al-Khudri narrated to him that he heard the Prophet, peace and blessings of Allah be upon him, saying: "Whoever performs five things in one day, Allah will record him among the people of Paradise: whoever fasts on a Friday, goes to the Friday prayer, attends a funeral, and frees a slave."
