What is the ruling on women performing hijama for a fee, given that the wife helps her husband pay off debts, fears showing off if she performs it for free, and bears the costs of hijama supplies?

The payment of the cupper is one of those rulings about which the apparent meanings of the evidence contradict, and the disagreement regarding it is old and widespread among scholars. Many scholars have held its permissibility without disapproval, interpreting the prohibition as one of dislike (karahah) and mild disapproval (tanzeeh). Al-Nawawi quoted from Al-Iqna' by Ibn Al-Mundhir that the cupper's earning is not unlawful, because the Prophet (peace be upon him) "gave the cupper his payment," and that the prohibition is one of mild disapproval, not prohibition. The majority have held that the cupper's payment is lawful, interpreting the prohibition as one of mild disapproval. The summary is that if a woman is in need of this profession, there is no harm for her in pursuing it, following those who permit it. However, if she is not in need, refraining from it is safer, as it avoids disagreement.
