Eid Mubarak
Eid al-Fitr was originated by the Islamic prophet Muhammad. It is observed on the first day of the Islamic month of Shawwal at the end of the month of Ramadan, during which Muslims undergo a period of fasting.
According to certain traditions, these festivals were initiated in Medina after the migration of Muhammad from Mecca. Anas (R.A) reports: When the Prophet arrived in Madinah, he found people celebrating two specific days in which they used to entertain themselves with recreation and merriment. He asked them about the nature of these festivities at which they replied that these days were occasions of fun and recreation. At this, the Prophet remarked that the Almighty has fixed two days [of festivity] instead of these for you which are better than these: Eid al-Fitr and Eid al-Adha
