Arabic (Original)
حَدَّثَنَا يَزِيدُ أَخْبَرَنَا هِشَامٌ عَنْ مُحَمَّدٍ عَنْ أَبِي هُرَيْرَةَ عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ إِذَا دُعِيَ أَحَدُكُمْ فَلْيُجِبْ فَإِنْ كَانَ صَائِمًا فَلْيَصِلْ وَإِنْ كَانَ مُفْطِرًا فَلْيَطْعَمْ.
English Translation
The Prophet (peace be upon him) said: 'When one of you is invited, let him respond. If he is fasting, let him pray (for the host). If he is not fasting, let him eat.'
