A few years ago, when Prof Dr Md Idris Mohd Noor was still alive, I asked his permission to convert his book to pdf format for use by UKM students. He agreed since the publisher had refused to print out new copies of the book.
So here is a pdf copy of the book. For users accessing it from within PPUKM internet connection, please click on this LINK instead. Please recite al-Fatihah on his behalf every time you use it. Whenever you recite the Yasin, please remember to include him in your prayers. May Allah bless us all, always.
