What is Eid?
Prophet Muhammad ﷺ created Eid for a reason. The day after Ramadan and another event. So basically they celebrate it two times a year. One is called Eid Al-Fitr and the other one is called Eid Al-Adha. Prophet Muhammad ﷺ wanted us to have a celebration for Muslims who have fasted. And Muslims normaly do Mehndi or should I call it Henna but you are not allowed to draw any eyes on your hand at all or else you are basically acting like the Hindus. According to Islam, as a Muslim you need to have a shower or a bath every Eid.
