Bulugh al-Maram 240
Narrated Anas (RA):
Allah's Messenger (ﷺ) said: "If supper is brought (and the prayer is ready) start with it (the food) before you pray the Maghrib (prayer)." [Agreed upon].
وَعَنْ أَنَسٍ‏- رَضِيَ اَللَّهُ عَنْهُ‏- أَنَّ رَسُولَ اَللَّهِ ‏- صلى الله عليه وسلم ‏-قَالَ : { إِذَا قُدِّمَ اَلْعَشَاءُ فَابْدَءُوا بِهِ قَبْلَ أَنْ تُصَلُّوا اَلْمَغْرِبَ } مُتَّفَقٌ عَلَيْهِ .‏ 1
