وَعَنْهُ أَيْضًا عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ إِذَا دَعَا أَحَدُكُمْ أَخَاهُ فَلْيُجِبْ عُرْسًا كَانَ أَوْ نَحْوَهُ
It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Noble Prophet (peace and blessings be upon him) said: When any one of you invites his brother, he should accept this invitation, whether it is a wedding invitation or any other.
