make love

Respected scholars, as-salamu `alaykum. If the husband wants to sleep with his wife but she does not want to and she is not sick and there is nothing wrong with her; she just does not like it, so he ends up sleeping with her by force, is this allowed in Islamic jurisprudence? Is this considered a kind of a rape? Today many self-styled Islamic clerics claim that this is totally permissible according to the authentic narrations of Prophet Muhammad (peace and blessings be upon him). Jazakum Allahu Khayran.
