وَعَنْ أَبِي شُرَيْحٍ الْكَعْبِيِّ
أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «مَنْ كَانَ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الْآخِرِ فَلْيُكْرِمْ ضَيْفَهُ جَائِزَتُهُ يَوْمٌ وَلَيْلَةٌ وَالضِّيَافَةُ ثَلَاثَةُ أَيَّامٍ فَمَا بَعْدَ ذَلِكَ فَهُوَ صَدَقَةٌ وَلَا يَحِلُّ لَهُ أَنْ يَثْوِيَ عِنْدَهُ حَتَّى يُحَرِّجَهُ»
The Prophet (sallallahu alayhi wa sallam) said:, “He who believes in God and the last day should honour his guest. Provisions for the road are what will serve for a day and a night; hospitality extends for three days; what goes beyond that is sadaqa; and it is not allowable that a guest should stay till he makes himself an encumbrance.”
