What did the Prophet Muhammad (peace be upon him) say about fasting on the days of Adha and Fitr at the end of Ramadan?
 Qaza'a related from Abu Sa'id. He said:                      I heard from him (Abu Sa'id) a hadith which impressed me, and I said to him: Did you hear it from the Messenger of Allah (may peace be upon him)? Thereupon he said: (Is it possible) that (I should) say about the Messenger of Allah (may peace be upon him) that which I have not heard? I heard him saying: It is not proper to fast on two days, Adha and Fitr (at the end) of Ramadan.
