Musannaf Ibn Abi Shaybah

Hazrat Abu Abdullah Al-Jadali narrates that Prophet Dawood used to supplicate as follows: O Allah! I seek refuge in You from the eye of the neighbor that watches me and from his heart that keeps surveillance over me. If he sees any good, he conceals it. And if he sees any evil, he spreads it.

Hazrat Ibn Abi Mulaika narrates that when food for iftar was brought to Hazrat Ibn Abbas (may Allah be pleased with them), he would supplicate before eating, and we have been informed that supplication is accepted before this.
