Hajj and Tawheed: Hajj is to set out for Makkah to worship Allah by performing certain religious rights in accordance with the Prophet's (peace and blessings be upon him) Sunnah. It is a time in which to call upon Allah to purify the self from any worship to anyone other than him. This booklet explains the basic rights of Hajj. It also notes that the tawheed of Allah requires the Muslim to follow the perfect way of worship, demonstrated by Muhammad (peace and blessings be upon him) and as understood by the Sahaabah who were the best of mankind.

The universality of Islam is an undeniable fact, a characteristic peculiar to Islam, the Righteous Religion. Almighty Allah has assigned Muhammad Ben Abdullah as Prophet and Messenger to the entire mankind, revealing to him His Holy Book to serve as a means of guidance and a reminder to all humanity. It was the will of Almighty Allah to make the Islamic Message the seal of revealed messages, which thus gave form and substance to the Righteous Religion.

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.
