A Brief Description of Islam as the Shi'ites Believe
A- THE UNITY OF ESSENCE
By that we mean: His absolute Holy Essence is one, indivisible, and no one is similar or like unto him.
B- THE UNITY OF HIS ATTRIBUTES
By that we mean:- knowledge, power, Eternality (EVERLASTING and PRE-EXISTENCE) and all other qualities and attributes of Him are in His Essence and are exactly the very self of His Essence. This is contrary to His creatures whose qualities are different to that of their bodies, and from each other too. This is a critical point and is to be thought upon with minute care.
C- THE UNITY OF HIS ACTION (ACT)
By that we mean that any action, movement, or effect, throughout the existence, have their causes in His will. In other word every thing depends on Him.
"Allah is the creator of all things, and He is the GAURDIAN and Disposer of all affairs."
THE HOLY QURAN - S39: 62
"To Him belong the keys of the heavens and the earth. He enlarges and restricts the sustenance to whom He wills, for He knows all things well."
THE HOLY QURAN - S42: 12
