The author said in its introduction, "Nothing offends more the Christians than to cast doubt about the doctrine of the Trinity, the fountainhead of their faith. Since I grew up as a Christian, I know by heart that it will surely injure a devout follower of Christianity something he knew as true. But to lend a blind eye when I know better is far from righteousness since I am bound by the God's Commandments to guide those mislead by the false doctrine. It is a basic right of every individual to know the truth that will lead him to the right path.
One of the most detailed books describing the rulings of Hajj, Umrah, and visiting the Masjid of the Prophet (peace be upon him).
