Musnad Ahmad 3215
Musnad of 'Abdullah bin al-'Abbas bin 'Abdul-Muttalib from the Prophet
It was narrated from Ibn ‘Abbas (رضي الله عنه) that He invited his brother ‘Ubaidullah to eat on the day of Arafat, and he said, I am fasting. He said: You are leaders whose example is followed, I saw the Messenger of Allah (ﷺ) call for fresh milk on this day and he drank. On one occasion Yahya (one of the narrators) said:... Members of a household whose example is followed.
