Prophet Muhammad, God bless him and grant him peace, instructed Muslims to celebrate only two holidays: Eid al-Fitr, at the end of Ramadan, and Eid al-Adha, during the annual Hajj. Some Muslims, in imitation of Christian practice, celebrate the Mawlid an-Nabi, the birthday of Prophet Muhammad, God bless him and grant him peace, but this cannot be viewed as an Islamic celebration.
The date of birth of Prophet Muhammad in Islamic calendar is:12 Rabi al Awal (Mawlid an Nabi for Sunni Muslims), and17 Rabi al Awal (Mawlid an Nabi for Shia MuslimsTwelvers)
Eid, Ramadan and Mawlid al-Nabi Shia Muslims celebrate also Eid Ghadir that is the day prophet Muhammad SAWW declared Imam Ali a.s. as Caliph and leader of Muslims after prophet at Ghadir Khum.
Celebrating Mawlid, the Prophet Muhammad's birthday, is a controversial topic in Islam. Some Muslims believe it is permissible, while others consider it haram, or forbidden. It ultimately depends on individual beliefs and interpretations of Islamic teachings.
Muhammad, the Prophet of Islam, was born on the 12th of Rabi' al-Awwal in the Islamic calendar. While some Muslims celebrate his birthday, known as Mawlid al-Nabi, fasting on this day is not a common practice. In fact, fasting is typically encouraged during specific months like Ramadan, rather than on birthdays or celebratory occasions. Therefore, it is not customary for Muhammad or Muslims to fast on his birthday.
To express their happiness about the Birth of Muhammad, peace be upon Him.
