Allah's Messenger (saws) said:  “When any one of you intends to eat (meal), he should eat with his right hand, and when he (intends) to drink he should drink with his right hand,  for the Satan eats with his left hand and drinks with his left hand.”

Hafsah reported, "The Messenger of Allah (saws) reserved his right hand for eating, drinking, putting on his clothes, taking and giving.   He used his left hand for other actions."
