Musnad of 'Abdullah bin al-'Abbas bin 'Abdul-Muttalib from the Prophet
It was narrated that Ibn ‘Abbas (رضي الله عنه) said: The Prophet (ﷺ) of Allah led the people in praying two rak'ahs on the day of al-Fitr with no adhan and no iqamah, then he addressed them after the prayer. Then he took the hand of Bilal and went to the women and addressed them. Then after he left them he instructed Bilal to go back to them and tell them to give charity.
