All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger. We ask Allaah to exalt his mention as well as that of his family and all his companions.
We have already clarified in Fatwa 90435 that the only days of 'Eed that are confirmed in our religion are 'Eed Al-Fitr and 'Eed Al-Adh-haa. All other festivals are contrary to the principles of our religion, whether they are calculated according to the Islamic or the Christian calendar.
Allaah Knows best.
