On the authority of Abu Huraira (may Allah be pleased with him), that the Messenger of Allah (may the blessings and peace of Allah be upon him) said :

Let him who believes in Allah and the Last Day either speak good or keep silent, and let him who believes in Allah and the Last Day be generous to his neighbour, and let him who believes in Allah and the Last Day be generous to his guest.
