Show me an ayaah of Quran where it's forbidden to not force girls to wear hijab?

There is no specific verse in the Quran that explicitly states that girls must be forced to wear the hijab. In Islam, it is generally understood that individuals should choose to adhere to the teachings of the religion willingly and not be forced into it. The Quran emphasizes the importance of modesty and covering oneself, but it does not condone coercion or compulsion in matters of faith.
