Return to Islam movement

In fact, this is a well-written book investigating the significant contraries among popular Islamic sects and religions ( Mostly, Sunni and Shia) based on Islamic certitudes and self-evidences. The book's contents propose that the writer "Allamah Mansoor Hashemi Khorasani" deeply comprehends the Quran and Sunnah of the prophet Muhammad (PBUH), which has turned the book an auspicious choice for those who are interested in Islamic facts and realities, unbiasedly. Finally, as someone who has read it more than once, I highly recommend every Muslims to have a deep insight into the book, if they are supposed to gain knowledge in Islamic realm of study.
