Is it permissible to act upon the opinion of Ibn al-Jawzi regarding the shaping of the eyebrows, where he holds that the prohibition is based on deception or that it is a mark of immoral women, knowing that the purpose is to tidy them and not to thin them? And is plucking (al-Nams) like other controversial issues in which it is permissible to adopt the easier opinion?

Plucking (namṣ) is absolutely forbidden, except for removing excess hair that causes disfigurement or an aesthetic defect. In matters of scholarly dispute, a Muslim acts according to what he believes to be the truth, either by examining the evidence and acting upon the strongest opinion if qualified, or by emulating the one he trusts most if not qualified. When opinions are equally valid, scholars have differed: some say one should follow the stricter opinion out of caution, some say one may adopt any of the opinions as long as one does not intend to seek out dispensations, and some say one should adopt the easier opinion because the Shari'ah is built upon facilitation. However, when one opinion is demonstrably stronger, then adopting it is obligatory.
