It is not prescribed for a person to fast on the day of his birth

Question:
May Allah reward you. He says: Honorable Shaykh, what is the ruling on fasting Thursday and Friday consecutively, or fasting on Friday sometimes but not always? Thank you to Allah the Exalted. It is my birthday, although I sometimes fast on Thursdays and Mondays.

Answer:
As for fasting on the occasion of one's birth, this is not prescribed, and it is a bid'ah (religious innovation). It is not permissible for you to perform any special act of worship or otherwise on your birthday, because this is adopting it as a festival. There is an explicit prohibition against imitating the disbelievers, and this is an imitation of the disbelievers, who celebrate the days of their births, and the births of their prophets and great men. This is an imitation of them. The Messenger (peace and blessings be upon him) said: And the Muslims have only two festivals: 'Id al-Fitr and 'Id al-Adha. Therefore, it is not permissible for you to celebrate your birthday. As for fasting, it is disliked to single out Friday for fasting. It is disliked to single out Friday for fasting due to the prohibition that came regarding it. Yes.
