: "Hospitality is for three days, and his reward is a day and a night, and whatever is spent on him after that is charity. And it is not lawful for him (the guest) to stay so long as to cause him harm."
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ الضِّيَافَةُ ثَلاَثَةُ أَيَّامٍ وَجَائِزَتُهُ يَوْمٌ وَلَيْلَةٌ وَمَا أُنْفِقَ عَلَيْهِ بَعْدَ ذَلِكَ فَهُوَ صَدَقَةٌ وَلاَ يَحِلُّ لَهُ أَنْ يَثْوِيَ عِنْدَهُ حَتَّى يُحْرِجَهُ وَفِي الْبَابِ عَنْ عَائِشَةَ وَأَبِي هُرَيْرَةَ وَقَدْ رَوَاهُ مَالِكُ بْنُ أَنَسٍ وَاللَّيْثُ بْنُ سَعْدٍ عَنْ سَعِيدٍ الْمَقْبُرِيِّ
