عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ رَضِيَ اللَّهُ عَنْهُمَا قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ إِذَا دُعِيَ أَحَدُكُمْ فَلْيُجِبْ فَإِنْ شَاءَ طَعِمَ وَإِنْ شَاءَ تَرَكَ
Narrated by Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) that the Noble Prophet (peace and blessings be upon him) said: When any of you is invited, he should accept the invitation; then if he wishes, he may eat, and if he wishes, he may not eat.
