The feast that ends Ramadan — new clothes, sweets, and giving before the prayer.
Ramadan is a month of fasting from dawn to sunset; Eid al-Fitr is the morning it ends. Because the Islamic calendar is lunar and the month begins with the sighting of the new moon, the date moves through the seasons and may differ by a day between countries. Before the Eid prayer, every household gives zakat al-fitr so that nobody is left out of the feast.
The giving happens before the eating, and it is required, not optional. That ordering is the lesson.
Something new to wear, something sweet to eat, and something given away first.
