Hadith 1429

Ibn Umar (Allah be pleased with him) reported that Allah's Messenger (may peace be upon him) said: When any one of you is invited to a feast, he should attend it.

حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، قَالَ قَرَأْتُ عَلَى مَالِكٍ عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ إِذَا دُعِيَ أَحَدُكُمْ إِلَى الْوَلِيمَةِ فَلْيَأْتِهَا ‏"‏ ‏.‏
