[Machine] On the authority of the Prophet Muhammad ﷺ , he said, "When one of you is invited to an invitation, let him respond and attend it." He also said, "Ibn Umar used to respond to invitations while fasting and while having broken his fast."
عَنِ النَّبِيِّ ﷺ قَالَ إِذَا دُعِيَ أَحَدُكُمْ إِلَى الدَّعْوَةِ فَلْيُجِبْ أَوْ قَالَ فَلْيَأْتِهَا قَالَ وَكَانَ ابْنُ عُمَرَ يُجِيبُ صَائِمًا وَمُفْطِرًا
When one of you receives an invitation (for a meal), he should accept it. If he isn to fasting, he should eat, and if he is fasten, he should pray. Hisham said: The word salat means to pray (for him to Allah). Abu Dawud said: This tradition has also been narrated by Hafs b. Ghiyath from Hisham. (Using translation from Abū Dāʾūd 2460)
قَالَ رَسُولُ اللهِ ﷺ «إِذَا دُعِيَ أَحَدُكُمْ إِلَى الدَّعْوَةِ فَلْيُجِبْ فَإِنْ كَانَ صَائِمًا فَلْيُصَلِّ وَإِنْ كَانَ مُفْطِرًا فَلْيَطْعَمْ»
