Musnad Ahmad 3064
Musnad of 'Abdullah bin al-'Abbas bin 'Abdul-Muttalib from the Prophet
It was narrated from Ibn 'Abbas (رضي الله عنه) that The Prophet (ﷺ) set out from Madinah in Ramadan with ten thousand Muslims. That was eight and a half years after he came to Madinah. He and the Muslims with him travelled towards Makkah; he was fasting and they were fasting too until, when he reached al-Kadeed, which is between ‘Usfan and Qudaid, he broke his fast and the Muslims with him broke their fast, then he did not fast.
