It is derived from the Hebrew words "din" meaning "to judge" and "el" referring to God. The name has its origins in the ancient Hebrew culture and can be traced back to the Old Testament of the Bible.

Daniel's wisdom and prophetic abilities are depicted in the book, and he is portrayed as a righteous man who remained faithful to his God despite the challenges he faced in a foreign land.

One of the earliest recorded individuals with the name Daniel was Daniel the Prophet, who lived during the 6th century BC. He is a significant figure in Judaism, Christianity, and Islam, and his book is included in the Hebrew Bible, the Christian Old Testament, and the Islamic Quran.
