(19) باب الْحَثِّ عَلَى إِكْرَامِ الْجَارِ وَالضَّيْفِ وَلُزُومِ الصَّمْتِ إِلاَّ مِنَ الْخَيْرِ وَكَوْنِ ذَلِكَ كُلِّهِ مِنَ الإِيمَانِ
It is reported on the authority of Abu Huraira that the Messenger of Allah (ﷺ) observed:
He who believes in Allah and the Last Day should either utter good words or better keep silence; and he who believes in Allah and the Last Day should treat his neighbour with kindness and he who believes in Allah and the Last Day should show hospitality to his guest.
