Bakkah (Arabic: بكة) is an ancient name for Mecca, the most holy city of Islam. Most people believe they are synonyms, but to Muslim scholars there is a distinction: Bakkah refers to the Kaaba and the sacred site immediately surrounding it, while Mecca is the name of the city in which they are both located.
According to Lisan Al Arab of Ibn Manzor, the site of Kaaba and its surroundings was named Bakkah due to crowding and congestion of people in the area. The Arabic verb bakka (بكَّ), with double "k", means to crowd like in a bazaar. This is not to be confused with another unrelated Arabic verb baka (بَكَى)(single k) which is the past participle of yabki (يَبْكِي), to cry.
Bakkah is mentioned in sura 3 (Al-i-Imran), ayah 96 of the Qur'an,Translation: " Verily the first House set apart unto mankind was that at Bakka, blest, and a guidance unto the worlds.".
Bakkah (also transliterated Baca, Baka, Bakke, Bakah, Bakka, Becca, Bekka, etc.) is the ancient name for the site of Mecca. An Arabic language word, its etymology, like that of Mecca, is obscure.
One meaning ascribed to it is "narrow", seen as descriptive of the area in which the valley of the holy places and the city of Mecca are located, pressed in upon as they are by mountains. Widely believed to be a synonym for Mecca, it is said to be more specifically the early name for the valley located therein, while Muslim scholars generally use it to refer to the sacred area of the city that immediately surrounds and includes the Kaaba.
The form Bakkah is used for the name Mecca in the Quran in 3:96, while the form Mecca is used in 48:24. In South Arabic, the language in use in the southern portion of the Arabian Peninsula at the time of Muhammad, the b and m were interchangeable. The Quranic passage using the form Bakkah says: "The first sanctuary appointed for mankind was that at Bakkah, a blessed place, a guidance for the peoples." Other references to Mecca in the Quran (6:92, 42:5) call it Umm al-Qura, meaning "mother of all settlements".
