The Feast of Ramadan
Ramadan is an Islam celebration of honor and faith. To comprehend the said event it is important to be aware first about the origins of Islam.
The Prophet Muhammad (Mohammad, Mohammed) was born in Mecca in 570 A.D. When he was 40 years old, the Angel Gabriel appeared to him and told him he was called to become a messenger of God. She taught him the verses of the Holy Koran, the Holy book of Islam. In Arabia at that point in time, there was a belief in many Gods. Muhammad taught that there was only one God- Allah, which means God in Arabic. The word Muslim literally means “one who gives himself to God” in Arabic. Islam means “submission or obedience to God.”
Muslims do not eat pork, but other meats are allowed, and animals must be killed in a way painless.
The passage of the Holy Koran is that Allah is the creator of the world. Muslims should surrender to the willpower of Allah.
The Five Pillars of Islam (Arabic: أركان الإسلام) is the term given to the five duties incumbent on every Muslim. These duties are Shahadah(profession of faith), Salat (ritual prayer), Zakat (alms giving), Sawm (fasting during Ramadan), and Hajj (pilgrimage to Mecca). These five practices are essential to Sunni Islam. Shi'a Muslims subscribe to eight ritual practices which substantially overlap with the Five Pillars. Twelvers have five fundamental beliefs which relates to Idahoan. 
The concept of five pillars is taken from the Hadith collections, notably those of Sahih Al-Bukhari and Sahih Muslim. The Qur'an does not speak of five pillars, although one can find in it scattered references to their associated practices.
The Feast of Ramadan
Ramadan is the ninth month of the Islam calendar.
Muslims believe that is was during the month of Ramadan that Mohammed, the prophet, received the Quran from Allah (God). At the end of Ramadan, the Id-al-Fitr (eed-al-fit-er), or the Feast of the Fast Breaking, is celebrated. Eid means recurring happiness or festivity . Greetings of "Eid-Mubarak" or "a blessed Eid" are exchanged. A very important aspect of eid is the charity which all the Muslims are expected to extend to the needy. The first Eid of the year, is known as "Eid Al Fitr". Al Fitr literally means breaking of fast. Thus Eid Al Fitr is celebrated on the first day of Shawaal, the tenth month in the Muslim calendar, to mark the end of a month long fast during the month of Ramadan. It is considered unholy to fast on this day. It is also a day of forgetting old grudges and ill feelings towards other fellow men.
