Honour your guest
مَنْ كَانَ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الْآخِرِ فَلْيُكْرِمْ ضَيْفَهُ
Man kana yu'minu billahi wa-l-yawmi-l-akhiri fa-l-yukrim dayfah.
"Whoever believes in Allah and the Last Day, let him honour his guest."
Narrated by Abu Hurayrah. Sahih al-Bukhari 6018, Sahih Muslim 47
A short reflection
The same hadith continues: let him speak good or be silent, let him honour his neighbour. Three behaviours pegged directly to iman, not to taste.
