Abu Hurairah (May Allah be pleased with him) reported:
Messenger of Allah (ﷺ) said, "He who believes in Allah and the Last Day, let him be hospitable to his guest; and he who believes in Allah and the Last Day, let him maintain good the ties of blood relationship; and he who believes in Allah and the Last Day, must speak good or remain silent".[Al-Bukhari and Muslim].
