Sahih
حَدَّثَنَا أَحْمَدُ بْنُ يُوسُفَ السُّلَمِيُّ، حَدَّثَنَا أَبُو عَاصِمٍ، أَنْبَأَنَا ابْنُ جُرَيْجٍ، عَنْ أَبِي الزُّبَيْرِ، عَنْ جَابِرٍ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " مَنْ دُعِيَ إِلَى طَعَامٍ وَهُوَ صَائِمٌ فَلْيُجِبْ فَإِنْ شَاءَ طَعِمَ وَإِنْ شَاءَ تَرَكَ " .
It was narrated from Jabir that the Messenger of Allah (ﷺ) said:“Whoever is invited to eat when he is fasting, let him accept the invitation; and if he wants to let him eat, and if he wants let him not eat.”
