It was narrated from Ibn "Abbas that

the Prophet (ﷺ) set out on the day of the conquest and he was fasting, then when he was in al-Kadeed, he broke his fast, and it is only what the Messenger of Allah (ﷺ) did last that is to be followed. It was said to Sufyan: With regard to the words, it is only what the Messenger of Allah (ﷺ) did last that is to be followed, are these the words of az-Zuhri or of Ibn "Abbas? He said: This is how it appears in the hadeeth.
