Wearing false eyelashes and nails

It is not permissible to wear false eyelashes because this comes under the ruling on wearing hair extensions. Wearing false nails that are long and look like the claws of wild animals is something that has come to us from the kuffaar; our sharee’ah enjoins us to cut our nails and not let them grow long, so why would we want to go against our sharee’ah? We ask Allah to guide us.
