Some Ans. Questions 2014 by -'Abdu'l-Bahá- 1 Para

Know that infallibility is of two kinds: infallibility in essence and infallibility as an attribute. The same holds true of all other names and attributes: For example, there is the knowledge of the essence of a thing and the knowledge of its attributes. Infallibility in essence is confined to the universal Manifestations of God; for infallibility is an essential requirement of Their reality, and the essential requirement of a thing is inseparable from the thing itself. The rays are an essential requirement of the sun and are inseparable from it; knowledge is an essential requirement of God and is inseparable from Him; power is an essential requirement of God and is likewise inseparable from Him. If it were possible to separate these from Him, He would not be God. If the rays could be separated from the sun, it would not be the sun. Therefore, were one to imagine the Most Great Infallibility being separated from the universal Manifestation of God, He would not be a universal Manifestation and would lack essential perfection (45:2)
