A sufi did not pray for 12 years

Well, I think its just a misconceptions or some people try to make false statmen or incomplete iformation.

If you try to search net you will also find many strange things said about these sufis which is agains Islam , and people try to say these sufis say this , I ask a question from these people , In pakistan mostly the Islam is spread by these sufis and we never heard such wrong thing nor apply in our life , this mean these sufis never speread some thing against Islam.
