The chapter is named "The Cow" in English, and its name in Arabic is "Al-Baqarah" which is derived from the story of the cow mentioned in the opening verses of the sura. It is considered one of the most important suras of the Quran, as it covers a wide range of topics such as the Oneness of God, the role of Prophet Muhammad as a messenger of God, and the principles of Islamic belief and practice.
