Guidance Needed For An Atheist Seeking God Through Intellectual Reasoning
Its very difficult to guide step by step approach without knowing that person personally. With my experience, i can suggest that the best arguments for God is only given in Quran. Just provide that person a good translation in their language. If they read and have question, you can guide them to Ghamidi sb Albayan or Molana Ahsan taddabur Quran in English or Urdu.
