Anas b. Malik reported:
حَدَّثَنَا هَارُونُ بْنُ سَعِيدٍ الأَيْلِيُّ ، حَدَّثَنَا ابْنُ وَهْبٍ ، أَخْبَرَنِي عَمْرٌو ، عَنِ ابْنِ شِهَابٍ ، قَالَ حَدَّثَنِي أَنَسُ بْنُ مَالِكٍ ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " إِذَا قُرِّبَ الْعَشَاءُ وَحَضَرَتِ الصَّلاَةُ فَابْدَءُوا بِهِ قَبْلَ أَنْ تُصَلُّوا صَلاَةَ الْمَغْرِبِ وَلاَ تَعْجَلُوا عَنْ عَشَائِكُمْ " .
The Messenger of Allah (ﷺ) said: When the supper is brought before you, and it is also the time to say prayer, first take food before saying evening prayer and do not hasten (to prayer, leaving aside the food).
