Eid al-Fitr (Arabic: عيد الفِطر) is one of the greatest religious holidays in Islamic tradition which marks the end of Ramadan. Fitr means opening and since in this day (Shawwal 1) Muslims break one month of fasting is called Eid al-Fitr. There are some verses and hadiths that mention the importance of this day.

It is quoted from Jabir who quoted from Imam al-Baqir (a) and he (a) quoted from the Prophet (s) saying, "when the first of Shawwal comes, the caller will call 'O believers! Rush to your rewards in the morning!" He (a) then said, "O Jabir! Rewards of God are not [like] the rewards of kings." And he (s) said, "That day is the day of rewards."
The Prophet (s) said, "angels on the day of Eid stand at the alleys and paths and say, 'rush to the Generous Lord who gives great blessings and forgives great sins."
