How many zer in quran?

The Quran contains the Arabic letter "ب" (which can be transliterated as "b") in various forms and contexts, but if you're referring to the number of times "zero" appears, it's important to note that the concept of "zero" as a number was not present in the Arabic language at the time the Quran was revealed. Therefore, the term "zero" does not appear in the Quran. If you meant something else, please clarify!
