Hadith 68

Sahih Bukhari

Book 10: Call to Prayers (Adhaan)

Chapter 42

(What should one do) if the meal has been served and the Iqama has been pronounced for As-Salat(the prayer)

باب إِذَا حَضَرَ الطَّعَامُ وَأُقِيمَتِ الصَّلاَةُ

And Ibn 'Umar used to start with the supper first. Abu Ad-Darda' said, "It is a sign of comprehension (of a person) to fulfil or turn to his needs first so as to offer prayer attentively with a clear mind." ​​
وَكَانَ ابْنُ عُمَرَ يَبْدَأُ بِالْعَشَاءِ. وَقَالَ أَبُو الدَّرْدَاءِ مِنْ فِقْهِ الْمَرْءِ إِقْبَالُهُ عَلَى حَاجَتِهِ حَتَّى يُقْبِلَ عَلَى صَلاَتِهِ وَقَلْبُهُ فَارِغٌ.
Sahih al-Bukhari 674
وَقَالَ زُهَيْرٌ وَوَهْبُ بْنُ عُثْمَانَ عَنْ مُوسَى بْنِ عُقْبَةَ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، قَالَ قَالَ النَّبِيُّ صلى الله عليه وسلم ‏ ‏‏.‏ رَوَاهُ إِبْرَاهِيمُ بْنُ الْمُنْذِرِ عَنْ وَهْبِ بْنِ عُثْمَانَ، وَوَهْبٌ مَدِينِيٌّ‏.‏
"‏ إِذَا كَانَ أَحَدُكُمْ عَلَى الطَّعَامِ فَلاَ يَعْجَلْ حَتَّى يَقْضِيَ حَاجَتَهُ مِنْهُ، وَإِنْ أُقِيمَتِ الصَّلاَةُ ‏"
Ibn `Umar:

The Prophet (ﷺ) said, "If anyone of you is having his meals, he should not hurry up till he is; satisfied even if the prayer has been started."
