According to a reliable tradition from the Holy Prophet (s.a.w.a.), one should give due respect to the bread, for it is the result of the hard work of many angels in heaven and men on the earth.
It is stated from Imam Ja’far-e-Sadiq (a.s.) that bread should not be kept under the bowl of curry.
Another tradition states that the Imam (a.s.) asked people to respect bread. The people questioned Imam (a.s.) as to how they should show their respect for bread. The Imam (a.s.) replied that one way is when the bread is kept before them, they should start eating it without waiting for anything.
According to a tradition from Imam Reza (a.s.), the bread should be baked in small loaves so that it may be sufficient for all groups.
