What is the religious ruling regarding a husband shaving his beard if his wife is harmed by it, even though it is a Sunnah?

Shaving the beard is considered forbidden by the majority of scholars due to the existence of religious texts that command its growth and preservation, and the differentiation from polytheists and Magians. If the wife is harmed by its growth, this is from the wiles of Satan, and divorcing her is less severe than committing what is forbidden.
