RamadhanKareem

Explained by the cleric Hanafi, that eating beyond the limit of satiety is illegal, except in two places (according to the muta'akhir ulama of the Hanafi School):

Increase the intake of strength to fast (eat sahur, not when breaking fast).
To compensate for a guest known to the host if he stops first, the guest also stops (because of shame / shrink) while the guest has not been satisfied. Under these circumstances, the host may eat as much as he can (until the guests are finished) so that he is not a class of people who do not glorify guests. "
