for example.

What did the Prophet Muhammad (saw) say about ladies who practice tattooing and artificially lengthen hair?
 Narrated Ibn `Umar:                     I heard the Prophet saying, (or the Prophet said), "Allah has cursed the lady who practices tattooing and that who gets it done for herself, and also the lady who lengthens hair artificially and that who gets her hair lengthened artificially." The Prophet has cursed such ladies.
