Musnad Abu Ya'la al-Mawsili 160:225

Ibrahim ibn ‘Ar‘arah narrated to us, Muhammad ibn Ma‘n narrated to us, my father narrated to us, from Sa‘id ibn Abi Sa‘id, from Abu Hurayrah, who said: The Messenger of Allah (may Allah bless him and grant him peace) said: "Whoever is pleased that his life be extended for him and his provision be expanded for him, then let him maintain his ties of kinship."
