Sahih al-Bukhari, Hadith 5464 ⓘ
Narrated Nafi: Once Ibn Umar was taking his supper while he was listening to the recitation of (Quran by) the Imam (in the Isha prayer).
وَعَنْ أَيُّوبَ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ عَنِ النَّبِيِّ صلى الله عليه وسلم نَحْوَهُ. وَعَنْ أَيُّوبَ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، أَنَّهُ تَعَشَّى مَرَّةً وَهْوَ يَسْمَعُ قِرَاءَةَ الإِمَامِ.
