When the supper is brought and the prayer begins, one, should first take food.  

عَنِ النَّبِيِّ ﷺ قَالَ إِذَا حَضَرَ الْعَشَاءُ وَأُقِيمَتِ الصَّلاَةُ فَابْدَءُوا بِالْعَشَاءِ  

The Messenger of Allah ﷺ said: When the supper is brought before you, and it is also the time to say prayer, first take food before saying evening prayer and do not hasten (to prayer, leaving aside the food).  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِذَا قُرِّبَ الْعَشَاءُ وَحَضَرَتِ الصَّلاَةُ فَابْدَءُوا بِهِ قَبْلَ أَنْ تُصَلُّوا صَلاَةَ الْمَغْرِبِ وَلاَ تَعْجَلُوا عَنْ عَشَائِكُمْ  

This hadith has been narrated on the authority of Anas by another chain of transmitters.  

عَنِ النَّبِيِّ ﷺ بِمِثْلِ حَدِيثِ ابْنِ عُيَيْنَةَ عَنِ الزُّهْرِيِّ عَنْ أَنَسٍ  

The Messenger of Allah ﷺ said: When the supper is served to any one of you and the prayer also begins. (in such a case) first take supper, and do not make haste (for prayer) till you have (taken the food).  

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا وُضِعَ عَشَاءُ أَحَدِكُمْ وَأُقِيمَتِ الصَّلاَةُ فَابْدَءُوا بِالْعَشَاءِ وَلاَ يَعْجَلَنَّ حَتَّى يَفْرُغَ مِنْهُ  

A hadith like this has been narrated from the Messenger of Allah ﷺ on the authority of Ibn 'Umar with another chain of transmitters.  

عَنِ النَّبِيِّ ﷺ بِنَحْوِهِ  

Al-Qasim was in the presence of 'A'isha (Allah be pleased with her) that I narrated a hadith and Qasim was a man who committed errors in (pronouncing words) and his mother was a freed slave-girl. 'A'isha said to him: What is the matter with you that you do not narrate as this son of my brother narrated (the ahaditb)? Well I know from where you picked it up. This is how his mother brought him up and how your mother brought you up. Qasim felt angry (on this remark of Hadrat 'A'isha) and showed bitterness towards her. When he saw that the table had been spread for 'A'isha, he stood up, 'A'isha, said: Where are you going? He said: (I am going) to say prayer. She said: Sit down (to take the food). He said: I must say prayer. She said: Sit down, ) faithless, for I have heard the Messenger of Allah ﷺ say: No prayer can be (rightly said) when the food is there (before the worshipper), or when he is prompted by the call of nature.  

تَحَدَّثْتُ أَنَا وَالْقَاسِمُ عِنْدَ عَائِشَةَ ؓ حَدِيثًا وَكَانَ الْقَاسِمُ رَجُلاً لَحَّانَةً وَكَانَ لأُمِّ وَلَدٍ فَقَالَتْ لَهُ عَائِشَةُ مَا لَكَ لاَ تَحَدَّثُ كَمَا يَتَحَدَّثُ ابْنُ أَخِي هَذَا أَمَا إِنِّي قَدْ عَلِمْتُ مِنْ أَيْنَ أُتِيتَ هَذَا أَدَّبَتْهُ أُمُّهُ وَأَنْتَ أَدَّبَتْكَ أُمُّكَ قَالَ فَغَضِبَ الْقَاسِمُ وَأَضَبَّ عَلَيْهَا فَلَمَّا رَأَى مَائِدَةَ عَائِشَةَ قَدْ أُتِيَ بِهَا قَامَ قَالَتْ أَيْنَ قَالَ أُصَلِّي قَالَتِ اجْلِسْ قَالَ إِنِّي أُصَلِّي قَالَتِ اجْلِسْ غُدَرُ إِنِّي سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ لاَ صَلاَةَ بِحَضْرَةِ الطَّعَامِ وَلاَ وَهُوَ يُدَافِعُهُ الأَخْبَثَانِ  

'Abdullah b. 'Atiq narrated from the Apostle ﷺ on the authority of 'A'isha, but he made no mention of the account of Qasim.  

عَنِ النَّبِيِّ ﷺ بِمِثْلِهِ وَلَمْ يَذْكُرْ فِي الْحَدِيثِ قِصَّةَ الْقَاسِمِ
