Millions of Christians abandon Christianity, Hindus become non practicing and leave their faith, there are thousands if not millions of non believing Jews but none of them come out and publish articles abandoning their religion except for someone who was or had converted to Islam, this is a common thread. Why because There’s a guilt and these people are looking for any support, any comment from like minded people saying yeah you did the right thing. Your research had been quite poor and going for Umrah isn’t going to bring a bolt of lightening for you. You want to understand Quran then get down to it and understand it from a teacher who knows, listen to Noman Ali Khan in English but seriously your so called research had been lower than poor.
