What did Allah's Apostle (saw) forbid people to do on the day they break fasting and the day on which they eat the meat of their sacrifices?
 Narrated Abu `Ubaid:                     (the slave of Ibn Azhar) I witnessed the `Id with `Umar bin Al-Khattab 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).
