Where does it say that the prophet cursed women who trimmed their eyebrows?

The Qur'an does not explicitly forbid trimming of the eyebrows, however many scholars believe that plucking and shaping the eyebrows for beauty is a form of changing the creation of Allah, as referred to in the following ayah:

4:119: And I [i.e., Satan] will mislead them, and I will arouse in them [sinful] desires, and I will command them so they will slit the ears of cattle, and I will command them so they will change the creation of Allah." And whoever takes Satan as an ally instead of Allah has certainly sustained a clear loss.

This is substantiated by the following hadith, in which Abdullah curses women who pluck their facial hair (i.e., the eyebrows) and claims the prophet did the same:

'Abdullah cursed those women who practiced tattooing and those who removed hair from their faces and those who created spaces between their teeth artificially to look beautiful, such ladies as changed what Allah has created. Um Ya'qub said, "What is that?" 'Abdullah said, "Why should I not curse those who were cursed by Allah's Apostle and are referred to in Allah's Book?" (Sahih Bukhari 7:72:822)

I know of nothing which prohibits or even discourages trimming the eyebrows, that is to say shortening the hairs of the eyebrow without actually removing them. Since trimming the hair of the head and trimming the mustache (for men) is not considered to be changing the creation of Allah — rather it is a form of beautification that was practiced by the prophet himself — I contend that trimming the eyebrows too would be acceptable.
