He who believes in Allah and the Last Day should honour his guest provisions for the road are what will serve for a day and night: hospitality extends for three days; what goes after that is sadaqah(charity): and it is not allowable that a guest should stay till he makes himself an encumbrance. Abu Dawud said: Malik was asked about the saying of the Prophet: "Provisions for the road what will serve for a day a night." He said: He should honor him, present him some gift, and protect him for a day and night, and hospitality for three days.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ مَنْ كَانَ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الآخِرِ فَلْيُكْرِمْ ضَيْفَهُ جَائِزَتُهُ يَوْمُهُ وَلَيْلَتُهُ الضِّيَافَةُ ثَلاَثَةُ أَيَّامٍ وَمَا بَعْدَ ذَلِكَ فَهُوَ صَدَقَةٌ وَلاَ يَحِلُّ لَهُ أَنْ يَثْوِيَ عِنْدَهُ حَتَّى يُحْرِجَهُ  

The Prophet ﷺ said: Hospitality extend for three days, and what goes beyond that is sadaqah (charity).  

أَنَّ النَّبِيَّ ﷺ قَالَ الضِّيَافَةُ ثَلاَثَةُ أَيَّامٍ فَمَا سِوَى ذَلِكَ فَهُوَ صَدَقَةٌ  

The Prophet ﷺ said: It is a duty of every Muslim (to provide hospitality) to a guest for a night. If anyone comes in the morning to his house, it is a debt due to him. If he wishes, he may fulfil it, and if he wishes he may leave it.  

قَالَ رَسُولُ اللَّهِ ﷺ لَيْلَةُ الضَّيْفِ حَقٌّ عَلَى كُلِّ مُسْلِمٍ فَمَنْ أَصْبَحَ بِفِنَائِهِ فَهُوَ عَلَيْهِ دَيْنٌ إِنْ شَاءَ اقْتَضَى وَإِنْ شَاءَ تَرَكَ  

The Prophet ﷺ said: If any Muslim is a guest of people and is given nothing, it is the duty of every Muslim to help him to the extent of taking for him from their crop and property for the entertainment of one night.  

قَالَ رَسُولُ اللَّهِ ﷺ أَيُّمَا رَجُلٍ أَضَافَ قَوْمًا فَأَصْبَحَ الضَّيْفُ مَحْرُومًا فَإِنَّ نَصْرَهُ حَقٌّ عَلَى كُلِّ مُسْلِمٍ حَتَّى يَأْخُذَ بِقِرَى لَيْلَةٍ مِنْ زَرْعِهِ وَمَالِهِ  

we said: Messenger of Allah! You send us out and we come to people who do not give hospitality, so what is your opinion? The Messenger of Allah ﷺ said: If you come to people who order for you what is fitting for a guest, accept it; but if they do not, take from them what is fitting for them to give to a guest. Abu Dawud said: And this is an authority for a man to take a thing if it is due to him.  

أَنَّهُ قَالَ قُلْنَا يَا رَسُولَ اللَّهِ إِنَّكَ تَبْعَثُنَا فَنَنْزِلُ بِقَوْمٍ فَمَا يَقْرُونَنَا فَمَا تَرَى فَقَالَ لَنَا رَسُولُ اللَّهِ إِنْ نَزَلْتُمْ بِقَوْمٍ فَأَمَرُوا لَكُمْ بِمَا يَنْبَغِي لِلضَّيْفِ فَاقْبَلُوا فَإِنْ لَمْ يَفْعَلُوا فَخُذُوا مِنْهُمْ حَقَّ الضَّيْفِ الَّذِي يَنْبَغِي لَهُمْ
