What is the ruling of Islamic law on a husband marrying without informing his wife, and on bringing the new wife to live with the first wife who refuses this, and does the Islamic religion have a stance on a woman's feelings in such cases?

Polygyny is permissible in Islamic law for a man, up to four wives, provided he can maintain justice. He is not obligated to inform his wife or seek her permission, though it is recommended for him to do so as a gesture of honor and to reassure her. He must deal justly between his wives. The wife is not obligated to accept the other wife residing in her private dwelling.
