حَدَّثَنَا إِسْمَاعِيلُ قَالَ‏:‏ حَدَّثَنِي مَالِكٌ، عَنْ سَعِيدٍ الْمَقْبُرِيِّ، عَنْ أَبِي شُرَيْحٍ الْكَعْبِيِّ، أَنَّ رَسُولَ اللهِ صلى الله عليه وسلم قَالَ‏:‏ مَنْ كَانَ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الْآخِرِ فَلْيَقُلْ خَيْرًا أَوْ لِيَصْمُتْ، وَمَنْ كَانَ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الْآخِرِ فَلْيُكْرِمْ ضَيْفَهُ جَائِزَتَهُ يَوْمٌ وَلَيْلَةٌ‏.‏ وَالضِّيَافَةُ ثَلاَثَةُ أَيَّامٍ، فَمَا بَعْدَ ذَلِكَ فَهُوَ صَدَقَةٌ، وَلاَ يَحِلُّ لَهُ أَنْ يَثْوِيَ عِنْدَهُ حَتَّى يُحْرِجَهُ‏.‏

Abu Shurayh al-Kabi al-Adawi (ra) has reported that the Messenger of Allah (ﷺ) said, "He who believes in Allah and the last day should speak a good, decent conversation otherwise remain silent. And he who believes in Allah and the last day should honour his guest whose Jaizah (a provision for the guest better than one’s own meals) is the length of a day and a night. And hospitality extends for three days and whatever is beyond that (more than three days) is Sadaqah. it is not proper for a guest to tax his host by overstaying (so that he is tired of him).
