Can I celebrate Eid if I converted during Ramadan?

Your Islam starts with a clean page

Islam wipes out what came before it. When Amr ibn al-As hesitated to accept Islam, worried about his past, the Prophet ﷺ told him that Islam erases what came before it (Sahih Muslim 121). The Quran says the same:

So the days of Ramadan before your shahada are not counted against you. Scholars agree you don't owe them.

What about the day you converted?

If you took your shahada during the daytime, scholars differ slightly. Many Hanafi and Hanbali scholars say you should stop eating for the rest of that day out of respect for Ramadan, and some say you then make up that one day. Others, including many Maliki and Shafi'i scholars, see holding back as only recommended. Either way, from the next day on you fast like everyone else if you're able to. If it was hard, go easy on yourself: you were just starting.

Zakat al-fitr is due on you

Because you were Muslim at the end of Ramadan, you pay zakat al-fitr like any other Muslim, about the cost of a meal or two per person. Pay it before the Eid prayer. See How much is zakat al-fitr and when do I pay it?

Make your first Eid count

• Go to the Eid prayer. It's short and easy to follow. See How do I pray the Eid prayer?
• Tell someone at the mosque that this is your first Eid. Many families love to invite new Muslims for lunch.
• Wear your best clothes, eat something sweet before the prayer, and say the takbir on the way.
• Share it with your family in a gentle way, even if they aren't Muslim, with food or a small gift.

If your first Eid feels quiet or lonely, that's common and it gets better each year. See What if I feel lonely on Eid as a new Muslim?
