Permissible for under-aged girls

Q 4: what is the ruling on a Mutabarrijah (a woman who makes a public display of her charms or adornment) who observes offering Salah (Prayer)?

A: She will be rewarded for her Salah; however, she will bear the major sin of being a Mutabarrijah. She has to repent to Allah (Exalted be He) and veil herself. Moreover, if she shows off her charms while performing Salah, her Salah will be invalid. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
