Musnad of 'Abdullah bin al-'Abbas bin 'Abdul-Muttalib from the Prophet
It was narrated that 'Abdullah bin ‘Abbas (رضي الله عنه) said: Then the Messenger of Allah (ﷺ) set out on his journey, and he appointed Abu Ruhm Kulthoom bin Husain bin ‘Utbah bin Khalaf al-Ghifari in charge of Madinah. He set out on the tenth of Ramadan; the Messenger of Allah (ﷺ) fasted and the people fasted, then when he was in al-Kadeed - an oasis between ‘Usfan and Amaj - he broke his fast, then he continued on until he halted in Marraz-Zahran with ten thousand Muslims
