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 lofty rank and high station eemaan possesses is not something obscure, as it is unquestionably, the most important duty as well as being the most imperative of all obligations.

Eemaan holds such a multitude of benefits, ripe fruits, delicious pro-duce, constant food and continual goodness.

Its author said in the introduction, "It is a known fact that every language has one or more terms that are used in reference to God and sometimes to lesser deities. This is not the case with Allah. Allah is the personal name of the One true God. Nothing else can be called Allah. The term has no plural or gender. This shows its uniqueness when compared with the word "god," which can be made plural, as in "gods," or made feminine, as in "goddess." It is interesting to notice that Allah is the personal name of God in Aramaic, the language of Jesus and a sister language of Arabic."
