It was narrated from Anas bin Malik that the Messenger of Allah (ﷺ) said:“If food is served and the Iqamah for prayer is given, then start with the food.”
حَدَّثَنَا هِشَامُ بْنُ عَمَّارٍ، حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنِ الزُّهْرِيِّ، عَنْ أَنَسِ بْنِ مَالِكٍ، أَنَّ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ قَالَ " إِذَا وُضِعَ الْعَشَاءُ وَأُقِيمَتِ الصَّلاَةُ، فَابْدَءُوا بِالْعَشَاءِ " .
