It was said to Sad Ibn Abee Waqqaas (radiyallaahu-anhu): ”Amongst the companions of the Messenger (sallal-laahu-alayhi-wasallam) your supplication is answered?” He said: ”I have never put a morsel of (food) in my mouth, except that I knew where it came from and where it originated.” [Jaami-ul Iloom Wal-Hikam: page: 115]
