Sahih Muslim
وَحَدَّثَنِي إِسْحَاقُ بْنُ مَنْصُورٍ، حَدَّثَنِي عِيسَى بْنُ الْمُنْذِرِ، حَدَّثَنَا بَقِيَّةُ، حَدَّثَنَا الزُّبَيْدِيُّ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مَنْ دُعِيَ إِلَى عُرْسٍ أَوْ نَحْوِهِ فَلْيُجِبْ " .
Ibn 'Umar (Allah be pleated with them) reported Allah's Messenger (ﷺ) having said: He who is invited to a wedding feast or like it, he should accept it.
