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.
It is reported on the authority of Abu Huraira that the Messenger of Allah (may peace and blessings be upon him) observed
He who believes in Allah and the Last Day does not harm is neighbour, and he who believes in Allah and the Last Day shows hospitality to his guest and he who believes in Allah and the Last Day speaks good or remains silent.
Another hadith similar to one narrated (above) by Abu Husain is also reported by Abu Huraira with the exception of these words
He (the Prophet) said: He should do good to the neighbour.
It is narrated on the authority of Abu Shuraih al-Khuzai' that the Prophet (may peace and blessings of Allah be upon him) observed
He who believes in Allah and the Last Day should do good to his neighbour and he who believes in Allah and the Last Day should show hospitality to the guest and he who believes in Allah and the Last Day should either speak good or better remain silent.
