Allah's Messenger (ﷺ) said, "Whoever believes in Allah and the Last Day should talk what is good or keep quiet, and whoever believes in Allah and the Last Day should not hurt (or insult) his neighbor; and whoever believes in Allah and the Last Day, should entertain his guest generously."
Sahih al-Bukhari Book 81, Hadith 64
← Previous Hadith Allah's Messenger (ﷺ) said, "Whoever can guarantee (the chastity of) what is between his two jaw-bones and what is between his two legs (i.e. his tongue and his private parts), I guarantee Paradise for him."

Sahih al-Bukhari Book 81, Hadith 63 Next Hadith → My ears heard and my heart grasped (the statement which) the Prophet (ﷺ) said, "The period for keeping one's guest is three days (and don't forget) his reward." It was asked, "What is his reward?" He said, "In the first night and the day he should be given a high class quality of meals; and whoever believes in Allah and the Last Day, should entertain his guest generously; and whoever believes in Allah and the Last Day should talk what is good (sense) or keep quiet."
