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.  

أَنَّ النَّبِيَّ ﷺ قَالَ إِذَا وُضِعَ عَشَاءُ أَحَدِكُمْ وَأُقِيمَتِ الصَّلاَةُ فَلاَ يَقُومُ حَتَّى يَفْرُغَ زَادَ مُسَدَّدٌ وَكَانَ عَبْدُ اللَّهِ إِذَا وُضِعَ عَشَاؤُهُ أَوْ حَضَرَ عَشَاؤُهُ لَمْ يَقُمْ حَتَّى يَفْرُغَ وَإِنْ سَمِعَ الإِقَامَةَ وَإِنْ سَمِعَ قِرَاءَةَ الإِمَامِ  

The Prophet ﷺ said: Prayer should not be postponed for taking meals nor for any other thing.  

قَالَ رَسُولُ اللَّهِ ﷺ لاَ تُؤَخِّرِ الصَّلاَةَ لِطَعَامٍ وَلاَ لِغَيْرِهِ  

Abdullah ibn Ubaydullah ibn Umayr said: I was with my father in the time of Ibn az-Zubayr sitting beside Abdullah ibn Umar. Then Abbad ibn Abdullah ibn az-Zubayr said: We have heard that the evening meal is taken just before the night prayer. Thereupon Abdullah ibn Umar said: Woe to you! what was their evening meal? Do you think it was like the meal of your father?  

عَبْدُ اللَّهِ بْنُ عُمَرَ وَيْحَكَ مَا كَانَ عَشَاؤُهُمْ أَتُرَاهُ كَانَ مِثْلَ عَشَاءِ أَبِيكَ
