Musannaf Ibn Abi Shayba 21:771

Muhammad ibn al-Hasan narrated to us, he said: Yahya ibn al-Muhallab narrated to us, from ‘Ata’ ibn al-Sa’ib, from Abu ‘Abd Allah al-Jadali, who said: The Prophet Dawud (peace be upon him) used to say: "O Allah, I seek refuge in You from a neighbor whose eye sees me, while his heart watches me; if he sees good, he buries it, and if he sees evil, he spreads it."
