"My eyes saw the Messenger of Allah, and my ears heard him speaking when he was speaking and he said: 'Whoever believes in Allah and the Last Day, then let him honor his guest with his reward.' They said: 'What is the reward?' He said: ' A day and a night.' He said: 'And hospitality is for three days, whatever is beyond that is charity. And whoever believes in Allah and the Last Day, then let him say what is good or keep silent."  

أَنَّهُ قَالَ أَبْصَرَتْ عَيْنَاىَ رَسُولَ اللَّهِ ﷺ وَسَمِعَتْهُ أُذُنَاىَ حِينَ تَكَلَّمَ بِهِ قَالَ مَنْ كَانَ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الآخِرِ فَلْيُكْرِمْ ضَيْفَهُ جَائِزَتَهُ قَالُوا وَمَا جَائِزَتُهُ قَالَ يَوْمٌ وَلَيْلَةٌ وَالضِّيَافَةُ ثَلاَثَةُ أَيَّامٍ وَمَا كَانَ بَعْدَ ذَلِكَ فَهُوَ صَدَقَةٌ وَمَنْ كَانَ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الآخِرِ فَلْيَقُلْ خَيْرًا أَوْ لِيَسْكُتْ  

: "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
