What were the two commands the Prophet Muhammad (saw) gave regarding breaking fast during a journey?
 It has been narrated on the authority of Zuhri with the same chain of transmitters that breaking of fast (in a journey) is the final of the two commands (whether one may fast or one may break it), and it is the last command of the Messenger of Allah (may peace be upon him) which is to be accepted as final. Zuhri said:                      The Messenger of Allah (may peace be upon him) marched on Mecca on the morning of 14th of Ramadan (lit. when thirteen nights had passed).
