Ibn 'Umar (Allah be pleated with them) reported Allah's Messenger having said: He who is invited to a wedding feast or like it, he should accept it.
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 " .
