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 not harm his neighbour; and he who believes in Allah and the Last Day let him show hospitality to his guest; and he who believes in Allah and the Last Day let him speak good or remain silent".[Al- Bukhari and Muslim].
