Backbiting:
{ The Messenger of God (Peace be upon him) has
described backbiting as: 'It is to mention about
a man what he does not want to hear.'
{ The Prophet (Peace be upon him) is reported
to have said: 'Backbiting implies your talking
about your brother in a manner which he does not like. If (that failing)
is actually found (in him) what you assert, you in fact backbited him,
and if that is not in him it is a slander.'
