Ja'far bin Muhammad bin 'Ali جعفر بن محمد بن علي - الصادق · Foods (Kitab Al-At'imah)

When the evening meal is brought before one of you and the congregational prayer is also ready, he should not get up until he finishes(eating). Musaddad’s version adds: When the evening meal was put before ‘Abd Allah b. ‘Umar, or it was brought to him, he did not get up until he finished it, even if he heard call to prayer(just before it), and even if he heard the recitation of the Qur’an by the leader-in-prayer.
