Volume 3, Book 31, Number 211:
Narrated Abu ‘Ubaid:
(the slave of Ibn Azhar) I witnessed the ‘Id with ‘Umar bin Al-Kattab who said, Allah’s Apostle has
forbidden people to fast on the day on which you break fasting (the fasts of Ramadan) and the day on
which you eat the meat of your sacrifices (the first day of ‘Id ul Fitr and ‘Id ul-Adha).
