Imam Sadiq (peace be upon him) says: Do you want to know how heavy the sin of slander is? The sin which you commit easily with that light tongue of yours. Its weightiness is much more than the mountains on the earth. Keeping one's prestige and honor is even more important than keeping one's property and lives. They put themselves in trouble for keeping their honor and dignity, they work hard, they even consider their honor and prestige more important than their health. However, there are people who simply say something and blacken someone's honor and dignity by backbiting and slandering.
