In Islam, there is nothing wrong that a Muslim attends a birthday party as long as one avoids committing something unlawful and there are no forbidden practices that are involved. The issue of celebration itself or the attendance should be governed by the rules of the Shari`ah. In this regard, Sheikh Faysal Mawlawi, Deputy Chairman of the European Council for Fatwa and Research, states the following regarding the Islam’s stance on celebrating birthdays:

“Permissibility is the original ruling in this case, as there is no evidence of prohibition.

Islam supports the celebration of birthdays if it is an expression of gratitude to Allah for His bounties, sustenance and blessings in man’s life, as long as that celebration does not include anything that may displease Allah,

Thus, there is nothing wrong in celebrating birthdays, as long as the celebration does not include any forbidden practices.”
