Whoever believes in Allah and the Last Day, let him say good words or remain silent. Whoever believes in Allah and the Last Day, let him be generous to his neighbor. Whoever believes in Allah and the Last Day, let him be hospitable to his guest. [Al-Bukhari]

"«من كان يؤمن بالله واليوم الآخر فليقل خيرًا أو ليصْمُت، ومن كان يؤمن بالله واليوم الآخر فليُكْرِم جارَه، ومن كان يؤمن بالله واليوم الآخر فليكرم ضَيْفَه». [البخاري.]"
