1: You feel that people who go to shrines and peers are not good Muslims and if Talibans have removed the peers or killed them that is a welcome sign from them and you link the downfall of the Muslim ummah to such activities i.e grave worshipping
2: Secondly you feel that Muslim ummah's downfall is because they are not following the quran
1: I stressed enough in my previous post that this is not the way to eradicate a problem, the only and best solution is educating people, using force in these issues will only create more trouble and in any case if using force is allowed then by now all Qadains should have been killed, Ghulam Ahmed Perwez (who was declared kafir by majority of the ulema should have been hanged as well and so on and so forth). Just go to Afghanistan and share your quranic views with talibans and then ask them whether they think they are the worst Muslims or your are the worst Muslim. If you still dont understand my point of view then please go to SWAT and open up a centre and start selling dr shabbir's books (you will understand why I am against using strength in such issues).
2: lets suppose muslims stop following Quran totally, do you think they wont make progress in this world?.That is what i meant when i wrote that progress doesn't ALWAYS need divine guidance. All the advancement in the world today is not because people read religious scriptures and then initiated their thinking process. it is a basic human trait to think, to ponder, to analyse, to invent etcetera. on the moral side Truthfulness, Honesty, Justice, Respect,fair play,Honest dealing etc are inherent in human nature and Humankind in general has a consensus on these moral values, one doesn't need to open up Quran to know that honesty is good and killing is bad.
that is what I mean when I use terms like common sense and basic human intellect and infer that straying away from Divine guidance in form of religious scriptures is not the sole reason of downfall of Muslim ummah.
