Sahih Muslim Book - 31, Hadith - 4513

حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ حَدَّثَنَا لَيْثٌ عَنْ سَعِيدِ بْنِ أَبِى سَعِيدٍ عَنْ أَبِى شُرَيْحٍ الْعَدَوِىِّ أَنَّهُ قَالَ سَمِعَتْ أُذُنَاىَ وَأَبْصَرَتْ عَيْنَاىَ حِينَ تَكَلَّمَ رَسُولُ اللَّهِ -صلى الله عليه وسلم- فَقَالَ « مَنْ كَانَ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الآخِرِ فَلْيُكْرِمْ ضَيْفَهُ جَائِزَتَهُ ». قَالُوا وَمَا جَائِزَتُهُ يَا رَسُولَ اللَّهِ قَالَ « يَوْمُهُ وَلَيْلَتُهُ وَالضِّيَافَةُ ثَلاَثَةُ أَيَّامٍ فَمَا كَانَ وَرَاءَ ذَلِكَ فَهُوَ صَدَقَةٌ عَلَيْهِ - وَقَالَ - مَنْ كَانَ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الآخِرِ فَلْيَقُلْ خَيْرًا أَوْ لِيَصْمُتْ ».

It was narrated that Abu Shurayh Al-'Adawi said: My ears heard and my eyes saw, when the Messenger of Allah (s.a.w) spoke and said: "Whoever believes in Allah and the Last Day, let him honor his guest with full hospitality." They said: What is full hospitality, O Messenger of Allah? He said: "One day and one night, and hospitality is for three days, and anything beyond that is charity towards him." And he (s.a.w) said: "Whoever believes in Allah and the Last Day, let him speak well or else remain silent."
