Hadith 4258
وَعَنْ أَبِي هُرَيْرَةَ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مِنَ السَّنَةِ أَنْ يَخْرُجَ الرَّجُلُ مَعَ ضَيْفِهِ إِلَى بَابِ الدَّارِ» . رَوَاهُ ابْن مَاجَه
Abu Huraira reported God's messenger as saying, "It is a part of the sunna that a man should accompany his guest to the door of the house." Ibn Majah transmitted it.
