the Messenger of Allah ﷺ said, 'If the supper is served for anyone of you and the Iqāmah is pronounced, start with the supper and don't be in haste (and carry on eating) till you finish it."
If food was served for Ibn ʿUmar and Iqama was pronounced, he never came to the prayer till he finished it (i.e. food) in spite of the fact that he heard the recitation (of the Qur'an) by the Imam (in the prayer).
قَالَ رَسُولُ اللَّهِ ﷺ: «إِذَا وُضِعَ عَشَاءُ أَحَدِكُمْ وَأُقِيمَتِ الصَّلاَةُ فَابْدَءُوا بِالْعَشَاءِ وَلاَ يَعْجَلْ حَتَّى يَفْرُغَ مِنْهُ۔»
وَكَانَ ابْنُ عُمَرَ يُوضَعُ لَهُ الطَّعَامُ وَتُقَامُ الصَّلاَةُ فَلاَ يَأْتِيهَا حَتَّى يَفْرُغَ وَإِنَّهُ لَيَسْمَعُ قِرَاءَةَ الإِمَامِ
