the correct workable URL is:
http://www.quranurdu.com/books/tafheem/Tafheem%20urdu/
It is Tafheem-ul-Quran by Maulana Maudoodi… english translation is also available .. check: http://www.quranurdu.com/books/tafheem
It’s pretty authentic dude… plus Islamicity website is definitely authentic as it has translation from major known translators like Pickthal and Yousuf Ali…
