Did any sect/denomination ascribe divinity to a person in the history of Islam ? If yes, what sect/denomination and who was the person? Also what were their basis for that ?
Ascribing divinity to a person would be considered shirk (associating others with Allah), which is considered the worst sin, and implies disbelief in Islam.
Indeed, Allah does not forgive association with Him, but He forgives what is less than that for whom He wills. And he who associates others with Allah has certainly fabricated a tremendous sin.
If a group ascribed divinity to a person, it would not be recognized as an Islamic group.
