Musnad Abu Ya'la al-Mawsili 154:116

Zuhayr narrated to us, Yazid bin Harun narrated to us, Asbagh bin Zayd al-Juhani informed us, Abu Bishr narrated to us, from Abu al-Zahiriyah, from Kathir bin Murrah al-Hadrami, from Ibn Umar, that the Prophet (peace be upon him) said: "Whoever hoards food for forty nights has dissociated from Allah, and Allah has dissociated from him. And whichever people of a courtyard (neighborhood/territory) have a hungry man among them when they wake up, the protection of Allah has dissociated from them."
