Of course they are wrong.

There are no basis of “shab-e-barat”and”shab-e-mairaj”in Quran and Hadis and it’s written no where that we should celebrate it or fast on those days. So the pansuras/Islamic books which show the nawafils and ayats we should read on those particular days so r all those pansuras/books nauzubillah wrong? Bcz if there is no basis of these events in Islam so from where did these nawafil come?
