Abu Shurayh reported: The Messenger of Allah, peace and blessings be upon him, said, “Whoever believes in Allah and the Last Day, let him honor his neighbor. Whoever believes in Allah and the Last Day, let him honor his guest and recompense him.” They said, “O Messenger of Allah, what is his recompense?” The Prophet said, “It is for a day and a night, as good hospitality is for three days and after that it is charity.” And the Prophet said, “Whoever believes in Allah and the Last Day, let him speak goodness or remain silent.”

عَنْ أَبِي شُرَيْحٍ الْعَدَوِيِّ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مَنْ كَانَ يُؤْمِنُ بِاللهِ وَالْيَوْمِ الْآخِرِ فَلْيُكْرِمْ جَارَهُ وَمَنْ كَانَ يُؤْمِنُ بِاللهِ وَالْيَوْمِ الْآخِرِ فَلْيُكْرِمْ ضَيْفَهُ جَائِزَتَهُ قَالُوا وَمَا جَائِزَتُهُ يَا رَسُولَ اللَّهِ قَالَ يَوْمُهُ وَلَيْلَتُهُ وَالضِّيَافَةُ ثَلَاثَةُ أَيَّامٍ فَمَا كَانَ وَرَاءَ ذَلِكَ فَهُوَ صَدَقَةٌ عَلَيْهِ وَقَالَ مَنْ كَانَ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الْآخِرِ فَلْيَقُلْ خَيْرًا أَوْ لِيَصْمُتْ
