Is it permissible to eat and drink with the left hand?

Is it permissible to eat and drink with the left hand? Could you please give the wisdom of eating with the right hand?

Dear Brother / Sister,

It is not haram to eat or drink with the left hand. However, eating wit the left hand is contrary to the eating manner of our Prophet; thus, that person will be deprived of thawabs (rewards). Therefore, it is necessary to get used to eating with the right hand beginning from the early ages.
