Just to elaborate .. on your second pointer.. in this case i wud say the politicians are the biggest angels living amongst us sinful ppl ..where they lie day in day out ..whyyy ..so they can save the dunya from fasad .. look where this is getting raja parvez ashraf with his lying about giving the pakistani nation some electric .. and as a result .. look on the flip side how mmany rallies and ihtijaaj there are going on ..
ps. could you give a referance as to where its written that it IS a saying of Hazrat Ali RA thankx.
