Yosef Karo

“ If somebody doesn't have any, they can trade with somebody else, this one sending to that one their meal, and this one sending to that one their meal, so that they can fulfill "And send portions, man to his fellow." ”

“ One who does more and one who does less [are both praiseworthy] , as long as they direct their heart toward heaven. One should not fast on Purim, except for a fast for a [bad] dream, and see 568 and 570. There are those who have the custom to dress in Shabbat/holiday clothes on Purim, and this is correct (Maharil) . We have the custom to make the Purim meal after the afternoon prayer and pray the evening prayer at night. We pray the afternoon prayer while most of the day remains, and most of the meal needs to be during the day (Minhagim) . ”

“ One should send the portions during the day and not at night (from the Ros"h ch. 1 of Megilla) . And if one sends portions to somebody else who will not accept them or forgives him, the obligation is fulfilled. And a woman is obligated in [sending] portions to the destitute and sending portions [to one's fellows] like a man is. A woman sends to a woman, a man to a man, but not the reverse, so that a man does not come to send it to a widow, leading to a possibility of kiddushin [having been enacted] . But regarding portions to the destitute one need not worry [about this possibility] . ”
