Muslims celebrate the festival of Eid.

Explanation:
Eid is a major festival celebrated by Muslims all over the world. It is a time of joy and happiness, and marks the end of the holy month of Ramadan, during which Muslims fast from dawn till dusk. There are two types of Eid celebrations in Islam: Eid al-Fitr and Eid al-Adha.

1. Eid al-Fitr:
Eid al-Fitr is celebrated at the end of the month of Ramadan. It is also known as the "Festival of Breaking the Fast". On this day, Muslims gather in mosques or open spaces to perform the Eid prayer. They wear new clothes, visit their friends and relatives, and exchange gifts and sweets. It is a day of forgiveness, charity, and thanksgiving.

2. Eid al-Adha:
Eid al-Adha is celebrated on the 10th day of the Islamic month of Dhu al-Hijjah. It is also known as the "Festival of Sacrifice". Muslims commemorate the willingness of Prophet Ibrahim (Abraham in the Bible) to sacrifice his son Ismail (Ishmael in the Bible) as an act of obedience to Allah. However, Allah replaced Ismail with a sheep just as Ibrahim was about to sacrifice him. On this day, Muslims slaughter an animal (usually a sheep, goat or cow) and distribute the meat to the poor and needy. It is a day of sacrifice, charity, and unity.

In conclusion, Eid is a significant festival celebrated by Muslims worldwide. It is a time of joy, forgiveness, and charity, and emphasizes the importance of unity and brotherhood among Muslims.
