The author’s statement in the chapter on the zakah of camels: “The obligatory amount does not change until it reaches thirty and one hundred.” What does this mean?

Question : The category does not change until it reaches the specified number.

Answer : Yes, that is correct. I mean that one hundred and twenty-one does not change the category to that of one hundred and twenty. It remains so until it reaches one hundred and thirty. So, instead of one hundred and twenty, we consider it one hundred and thirty. However, the correct view is the first one, because it is what is indicated by the hadith of Abu Bakr (may Allah be pleased with him), which states that one hundred and twenty-one changes the category.
