Is it valid to attribute the permissibility for a woman to trim her eyebrows for her husband to Ibn al-Qayyim, and was this mentioned in his books?

This clarifies the ruling on a married woman taking anything from her eyebrows. A Muslim must adhere to what conforms to the Quran and Sunnah, and beware of disobeying the command of the Messenger of Allah, peace and blessings be upon him, for Allah Almighty says: {And let those who oppose His command beware, lest a trial strike them or there come upon them a painful punishment} (An-Nur: 63), and His saying: {And whatever the Messenger has given you - take it; and what he has forbidden you - refrain from it} (Al-Hashr: 7). And whoever opposes the authentic and established text from the Prophet, peace and blessings be upon him, after its clarity, is included in the warning of His saying, the Almighty: {And whoever opposes the Messenger after guidance has become clear to him and follows other than the way of the believers - We will give him what he has taken and drive him into Hell, and evil it is as a destination} (An-Nisa: 115).
