Defination Of Tawheed

Literally Tawhid means “unification” (making something one) or “asserting oneness,” and it comes from the Arabic verb “wahhada” which itself means to unite, unify, or consolidate.
 

However, when the term Tawheed is used in reference to Allah (i.e. Tawhidullah), it means realizing and maintaining of Allah’s unity in all of man’s actions which directly or indirectly relate to Him.

Allaah, the Mighty and Majestic, alone and the abandonment of worship to others besides Him. As He, the Most High, said:“And verily, We have sent amongst every nation, a messenger (proclaiming): “Worship Allaah (alone) and abandon the taaghoot  [an-Nahl (16):36]

The first thing that every prophet addressed his nation with was:

“Worship Allaah, you have no other ilaah (deity worthy of worship) but Him.” [al-A’raaf (7): 59]
 

It is the belief that Allah is One, without partner in His dominion (Rububiyah), One without similitude in His essence and attributes (Asma’ wa Sifat), and One without rival in His divinity and in worship (Uluhiyah / Ibadah).

These three aspects form the basis for the categories into which the science of Tawheed has been traditionally divided.The three overlap and are inseparable to such a degree that whoever omits any one aspect has failed to complete the requirements of Tawheed.

The omission of any of the above mentioned aspects of Tawheed is referred to as Shirk (lit. sharing); the association of partners with Allah.In Islamic terms, is in fact idolatry.

The three categories of Tawheed are commonly referred to by the following titles:

1. Tawhid Al-Rububiyah (lit. “Maintaining the Unity of Lordship”) that is, affirming that Allah is one, without partners in his sovereignty.

2. Tawhid Al-Asma’ wa Al-Sifat (lit. “Maintaining the Unity of Allah’s Names and Attributes,”) that is, affirming that they are incomparable and unique.

3. Tawhid Al-Ibadah (lit. “Maintaining the Unity of Allah’s Worship”) that is, affirming that Allah is alone in His right to be worshipped.
