Jami at-Tirmidhi
حَدَّثَنَا نَصْرُ بْنُ عَلِيٍّ، حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " إِذَا دُعِيَ أَحَدُكُمْ وَهُوَ صَائِمٌ فَلْيَقُلْ إِنِّي صَائِمٌ " . قَالَ أَبُو عِيسَى وَكِلاَ الْحَدِيثَيْنِ فِي هَذَا الْبَابِ عَنْ أَبِي هُرَيْرَةَ حَسَنٌ صَحِيحٌ .
Abu Hurairah narrated that : The Prophet Said: "When One Of You Is Invited (To A Meal) And He Is Fasting, Then Let Him Said: 'Indeed I Am Fasting.'"
