What is the lesson taught to us by the Prophet Muhammad (saw) regarding faith in Allah and the Last Day?
 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.
