Khaythamah bin Abd al-Rahman (may Allah have mercy on him) said: "The example of one who reviles the deceased is like that of a person standing on the brink of destruction; and the example of one who sits on the bed of a woman whose husband is away from home is like that of a person whose backside will be widened on the Day of Resurrection."
Clarification: This report contains a severe warning against reviling the deceased and against going to a non-mahram woman whose husband is not at home.
