My eare listened and my eye saw when Messenger of Allah ﷺ spoke and said: He who believes In Allah and the eireafter should show respect to the guest even with utmost kindness and courtesy. They said: Messenger of Allah, what is this utmost kindness and courtesy? He replied: It is for a day and a night. Hospitality extends for three days, and what is beyond that is a Sadaqa for him; and he who believes in Allah and the Hereafter should say something good or keep quiet. (Using translation from Muslim 48b)
قَالَ رَسُولُ اللهِ ﷺ مَنْ كَانَ يُؤْمِنُ بِاللهِ وَالْيَوْمِ الْآخِرِ فَلْيُكْرِمْ ضَيْفَهُ
