As per Islamic scriptures, Allah is the formless, limitless, transdental and unchanging Supreme God.
Prophet Muhammad describes Allah as both benevolent as well as fearsome. The word Allah is not new but is evolved
from El and Elah, the Hebrew words for God. Miteiya compares the benevolent and fearsome form of Allah with
Narsimha avatar of Vishnu.
Miteiya says that description of Allah has many similarities with Shiva of Sanatan Dharma. The main teaching of “Impermanence” suggests that all compounded things and processes are in fact formless. It is difficult for common people to comprehend “Formlessness”. Even the advance voyagers begin to perceive formlessness in some concrete form. This perception about “Formlessness” is also “Shankara”. Shivaism says, “Shankara is Shiva”, depicting the fact that compounded forms are nothing but formless. Prophet Muhammad hence suggests that a person who can see phenomenon, objects and processes, as formless manifestations is the wise man.
In a Surah called “Surah-al-Saffat”, Allah questions the intentions of the idol-worshippers on the “Judgment Day”. The faithfuls who resorted to idol-worshipping and giving respect to angels simply said: “We thought they would bring us close to you”. Hearing this, Allah said, “ if that is the case, I would look at it on its merit”. This necessarily means that one should refrain from angels and idols and worship one “Singular Formless God”. The same thing is explained in Sanatan Dharma, wherein people are recommended to refrain from idol worshipping and resort to “One Singular Formless God”.
While, idol worshipping had been widely accepted in Pagans and pre-Abrahamic tribes, the concept of “Formless supreme God” had been resurrected with the rise of Abraham. This concept of formlessness is in line with 4th chakra of meditation and 5th avatar of Vishnu, wherein God appears in an unprecedented form of “Narsimha”. God is hence considered as “Beyond Perceptions”.
