Note: This text in an extract from the book Haqqul Yaqeen by shaykh ul-islam Allama Muhammad Baqir Majlisi

It is clear that Allah, the Mighty and the High is eternal and ever-living. His non-existence is impossible. He is from ever and he shall remain for ever. It is so, because if He were incidental and non-existent and annihilation was possible for Him, He would be needful of another creator and He would not be a necessary being and the creator of the universe.

We should know that His existence is necessary and it is necessary for His being and it is impossible to separate it from His being. Followers of different religions have reached consensus on His being perfect from all aspects and that helplessness, defect and annihilation is Impossible for Him.
