Greetings,
The prohibition on backbiting has always unsettled me. The idea that speaking the truth can be seen as morally wrong is very strange to me.
You misunderstand. The ruling is there to prevent name calling/slander/general tattle taling.
Let's say in the streets of a sharia compliant state, I come up to your wife or female companion. Let's then say I call her a **** or ***** (women who fornicates freely). To her face, in front of the townsfolk. Let's then say I show some ''evidence'' of it.
What I have done is:
* caused YOU trouble (you now have doubts about her)
* caused YOUR female cohort trouble (she has now been blacklisted from the community as a whole and the comments I have made about her have spread like wild fire because humans are social beings and like to talk)
* caused anyone related or linked to you or her trouble (for same reasons)
Whether or not the claim has any truth in it, I have insulted that person (for no good reason). If I have told the truth, it is even worse because now I have told
everyone that persons sins (she has been blacklisted from the entire community as a result) - so it makes it even more difficult for her to gain any trust or respect back. Basically, I have in all intents and purposes just acted like the biggest ass in the world.
That is what the backbiting rule is to prevent: disrespecting and slandering people as a whole. Granted, the above example is a worst scenario case (and not neccessarily a common one) but I am sure you understand now. There is this saying that the truth hurts. So do lies.
Is it at all analogous to the Shia concept of taqiyya?
...
Taqiyya is to do with lying in order to protect oneself - different topic altogether.
