Musnad of 'Abdullah bin al-'Abbas bin 'Abdul-Muttalib from the Prophet
It was narrated from Ibn 'Abbas that the Messenger of Allah (ﷺ) went out humbly, beseeching, with humbleness, wearing shabby clothes and walking at a measured pace, then he led the people in praying two rak'ahs, like the Eid prayer, and he did not deliver a khutbah like this khutbah of yours.
