1) If you have a problem with grave-worshipping. Then you need to STOP the grave-worshipping, NOT the grave. 2) If you want to stop the grave-worship, then you need to show that it is Haram. Breaking graves without an explanation is not the answer. 3) If you are just a regular bloke on the street, you have no right to trespass on another's property and start vandalizing. 4) If you are the rulership or have taken-over rulership (like 'Ansar Dine' in Mali), then WHY do you need to Break the tombs?? Dont you have the power to Prevent grave-worship, and dont you have the power to Educate the laymen, since you're apparently "establishing Sharia rule"? 5) Once you have taken effective control of the state/region, "militant" activities are not needed, education/dawa is needed. Otherwise, you have established dictatorship/tyranny and not Sharia.
