Musnad Ahmad 3299
Musnad of 'Abdullah bin al-'Abbas bin 'Abdul-Muttalib from the Prophet
It was narrated that Ibn 'Abbas (رضي الله عنه) said: The Messenger of Allah (ﷺ) said: "Jibreel (as) led me in prayer at the House twice, then he said: 'O Muhammad, this is your time (of prayer) and the time of the Prophets before you.” He led him in praying Zuhr when a shadow was the length of a shoelace and he led him in praying Maghrib when the fasting person breaks his fast and food and drink become permissible.
