أَخْبَرَنَا مُحَمَّدُ بْنُ مَنْصُورٍ، قَالَ حَدَّثَنَا سُفْيَانُ، عَنِ الزُّهْرِيِّ، عَنْ أَنَسٍ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم إِذَا حَضَرَ الْعَشَاءُ وَأُقِيمَتِ الصَّلاَةُ فَابْدَءُوا بِالْعَشَاءِ .
It was narrated that Anas said: "The Messenger of Allah (ﷺ) said: 'If dinner is ready and the Iqamah for prayer is said, then start with dinner first."'
