Amanda, I can tell you about it. To first understand Eid, you must understand the holy month of Ramadan.
The month of Ramadan is the one in which the Qur'an was sent down as guidance for mankind, with Clear Signs containing guidance and discrimination. Any of you who are resident for the month should fast it. But any of you who are ill or on a journey should fast a number of other days. Allah desires ease for you; He does not desire difficulty for you. You should complete the number of days and proclaim Allah's greatness for the guidance He has given you so that hopefully you will be thankful. (Surat al-Baqara: 185)
You who believe! Fasting is prescribed for you, as it was prescribed for those before you, so that you may guard (against evil). (Surat al-Baqara: 183)
As is revealed in that verse, one of the reasons why fasting is obligatory is for people to avoid evil and restrain their desires. The only way to do that is to believe in Allah with a sincere heart, abide by His commands and recommendations and avoid the temptations of one's desires. Such a person's morality will grow ever more pleasing with time, his faith will mature and his fear of Allah grow stronger.
Ramadan is the month is which the Qur'an was revealed. This is also the month is which Muslims fast, from sunrise to sunset. But, it isn't only about abstaining from food. It's about controlling your desires because that's what Islam tries to teach Muslims, to control their desires. If you notice, it's when people go after their desires and do whatever they want to do when they lose touch with their faith. But, when a person learns to control their desires and not fall into Satans trap, their faith become stronger. This way, Muslims dont' fall into the trap that society wants us to be trapped in.
However, the important thing is that the pure faith, sincere prayer, care taken over the remembrance of Allah and attention to restraining one's desires acquired during the month of Ramadan should not weaken once it is over. A person with strong faith spreads the superior morality of Ramadan over every moment of his life. Allah has made fasting on certain days an obligation, and has commanded people to avoid wrongdoing. Yet one must avoid wrongdoing throughout one's life, listen to the voice of one's conscience, make efforts to win Allah's good pleasure with godly intent and turn only to Him. That is the morality that Allah will find pleasing.
The Prophet Mohammad (peace be upon him) has said, "Every community has their day of celebration and for the Muslims, their day of celebration is Eid." The reason we celebrate Eid is to celebrate the effort we put forth into the month of Ramadan. I hope that explains it all, as I think it should. If you have any more questions, don't be shy to ask.
glad you learned about it.. Now its Eid Al ad7a time
