Fasting (Kitab Al-Siyam)
14/77. Chapter:
What should a fasting person say when invited to a meal?
Sunan Abi Dawud
حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا سُفْيَانُ، عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " إِذَا دُعِيَ أَحَدُكُمْ إِلَى طَعَامٍ وَهُوَ صَائِمٌ فَلْيَقُلْ إِنِّي صَائِمٌ " .
Abu Hurairah reported Messenger of Allah (ﷺ) as saying: When one of you is invited (to a meal), and he is fasting, he should say that he is fasting.
