Some scholars are telling in their speeches that 4 persons will not be forgiven even in Ramadan or Lailatul Qadr-1- one who has disconnected with his relatives 2-who drinks alcohol 3-who has keena in his heart and 4-the one who disobeys his parents. They are attributing this as hadith of Rasulullah sallallahu alayhi wasallam. Is there any such hadith? Is this true that some types of people are not forgiven even on these great opportunities of Ramadan and lailatul qadr?
