BUKHARI 6476:
from Abū Shurayḥ al-Khuzāʿī —
My ears heard and my heart grasped (the statement which) the Prophet ﷺ said, "The period for keeping one's guest is three days (and don't forget) his reward." It was asked, "What is his reward?" He said, "In the first night and the day he should be given a high class quality of meals; and whoever believes in Allah and the Last Day, should entertain his guest generously; and whoever believes in Allah and the Last Day should talk what is good (sense) or keep quiet."

عن ابو شريح الخزاعي —
سَمِعَ أُذُنَاىَ وَوَعَاهُ قَلْبِي النَّبِيَّ ﷺ يَقُولُ الضِّيَافَةُ ثَلاَثَةُ أَيَّامٍ جَائِزَتُهُ قِيلَ مَا جَائِزَتُهُ قَالَ يَوْمٌ وَلَيْلَةٌ وَمَنْ كَانَ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الآخِرِ فَلْيُكْرِمْ ضَيْفَهُ وَمَنْ كَانَ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الآخِرِ فَلْيَقُلْ خَيْرًا أَوْ لِيَسْكُتْ
