Abd al-Rahman Ibn Hajjaj narrates:
We were in the house of Imam Sadiq (peace be upon him) and were having food with him when some more rice was brought for us. We sought to excuse ourselves from eating more whereupon the Imam (peace be upon him) said: Whoever likes us more shall consume more food with us.
Hearing this, we once again sat down and began eating the food. Witnessing this, the Imam (peace be upon him) stated: This is so much better.
He (peace be upon him) then continued: One day, the Holy Prophet (peace be upon him and his holy progeny) was presented with some rice, whereupon he (peace be upon him and his holy progeny) invited Salman, Abu Dharr and Miqdad to join him in eating it. They sought to excuse themselves but he (peace be upon him and his holy progeny) insisted: “Whoever likes us more ought to eat more with us.” Hearing this, all of them ate to their full.
