People say "talk is cheap". Anyone can say anything, but saying something just for the sake of saying something can get us into trouble. This is why Prophet Muhammad, peace and blessings of Allah be upon him taught us:
"Whoever believes in Allah and the Last Day should either say something good or keep silent."
(source: Al-Tirmidhi, Hadith 1376)
Muslim or not, don't we all say "If you don't have anything good to say, then don't say anything at all." Or at least its seems most people say it, so let's remember that and keep our mouths shut when we feel like exploding the most, or are in a mood for some gossipish entertainment that will do nothing but fry us deeper (really) and increase any vanity we already possess. We all know the right thing to do, so let's not be hypocrites.May Allah guide Muslims and non-Muslims in accepting all that Allah has given humanity within the true teachings of Islam.
