Is a woman sinful if she removes hair from between her eyebrows and feels that the one who plucked it accidentally took something from her eyebrows?

The fatwa we follow permits removing hair from between the eyebrows. This is not considered the forbidden namṣ (plucking), because namṣ is the removal of hair growing on the prominent bone directly above the eye. If what the woman removed was outside this boundary, there is no issue. However, if it was within it, and without your command or consent, and you did not notice her when she removed it, then we hope there is no sin upon you, and the sin is upon her if she did it intentionally.
