"Whoever believes in the Last Day, let him honor his guest, and grant him reward for a day and a night. And it is not permissible for him to stay so long that he causes annoyance to his host. Hospitality is for three days, and whatever he spends on him after three days is charity."  

عَنِ النَّبِيِّ ﷺ قَالَ مَنْ كَانَ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الآخِرِ فَلْيُكْرِمْ ضَيْفَهُ وَجَائِزَتُهُ يَوْمٌ وَلَيْلَةٌ وَلاَ يَحِلُّ لَهُ أَنْ يَثْوِيَ عِنْدَ صَاحِبِهِ حَتَّى يُحْرِجَهُ الضِّيَافَةُ ثَلاَثَةُ أَيَّامٍ وَمَا أَنْفَقَ عَلَيْهِ بَعْدَ ثَلاَثَةِ أَيَّامٍ فَهُوَ صَدَقَةٌ  

"We said to the Messenger of Allah ﷺ: ' You send us and we stay with people who do not show us any hospitality. WHat do you think of that?' The MEssenger of Allah ﷺ said: 'If you stay with people and they give you what a guest deserves, then accept it. If they do not do that , then take from them what they should have offered, which a guest is entitled to.'"  

أَنَّهُ قَالَ قُلْنَا لِرَسُولِ اللَّهِ ﷺ إِنَّكَ تَبْعَثُنَا فَنَنْزِلُ بِقَوْمٍ فَلاَ يَقْرُونَا فَمَا تَرَى فِي ذَلِكَ قَالَ لَنَا رَسُولُ اللَّهِ ﷺ إِنْ نَزَلْتُمْ بِقَوْمٍ فَأَمَرُوا لَكُمْ بِمَا يَنْبَغِي لِلضَّيْفِ فَاقْبَلُوا وَإِنْ لَمْ يَفْعَلُوا فَخُذُوا مِنْهُمْ حَقَّ الضَّيْفِ الَّذِي يَنْبَغِي لَهُمْ  

"The Messenger of Allah ﷺ said: ' Putting up a guest for one night is obligatory. If you find a guest at your door in the morning, then this (hospitality) is (like) a debt that you (the host) owe him. If he (the guest) wants, he may request it, and if he wants, he may leave it'"  

قَالَ رَسُولُ اللَّهِ ﷺ لَيْلَةُ الضَّيْفِ وَاجِبَةٌ فَإِنْ أَصْبَحَ بِفِنَائِهِ فَهُوَ دَيْنٌ عَلَيْهِ فَإِنْ شَاءَ اقْتَضَى وَإِنْ شَاءَ تَرَكَ
