God in Baha'i Faith and in Islam

"Both Islam and the Baha'i Faith are agreed on their descriptions of Allah including that there is only one God - Allah;

Islam:
There is no God but He: that is the witness of Allah, Hiss angles, and those endued with knowledge....There is no god but He, the Exalted in Power, Then fear Me (and Me alone). (16:51)


Baha'i:
Beware, beware, lest thou be led to join partners with the Lord, thy God. He is, and hath from everlasting been, one and alone, without peer or equal, eternal in the past, eternal in the future, detached from all things, ever-abiding, unchangeable, and self-subsisting. He hath assigned no associate unto Himself in His Kingdom, no counsellor to counsel Him, none to compare unto Him, none to rival His glory. To this every atom of the universe beareth witness, and beyond it the inmates of the realms on high, they that occupy the most exalted seats, and whose names are remembered before the Throne of Glory. (Gleanings from the Writings of Baha'u'llah, p. 192)"
