صحيح البخاري#673Sahihحَدَّثَنَا عُبَيْدُ بْنُ إِسْمَاعِيلَ، عَنْ أَبِي أُسَامَةَ، عَنْ عُبَيْدِ اللَّهِ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " 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.
Narrated Nafi`:Ibn `Umar said, "Allah's Messenger (ﷺ) said, 'If the supper is served for anyone of you and the Iqama 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 `Umar 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)
Scholarly Authentication
The label above is the grade most of these scholars gave — one dissenting opinion no longer speaks for all of them. If any scholar calls a narration fabricated, that verdict is shown instead, whatever the others say. Each scholar's own wording:
Every narration in Sahih al-Bukhari is accepted as Sahih (authentic) by the established status of the book.
