Is it permissible for him to go to his second wife if he forsakes his first wife for a shar’i reason?

Is it permissible for him to go to his second wife if he forsakes his first wife for a shar’i reason [i.e., withholds conjugal relations for disciplinary purposes]? Or should he stay in the same house with the wife whom he is forsaking?

Praise be to Allah, and blessings and peace be upon the Messenger of Allah:

We put this question to Shaykh Muhammad ibn Saalih al-‘Uthaymeen, may Allaah preserve him, who answered as follows:

For the sake of dividing his time fairly among his wives, giving each wife a night and a day, he should stay with her. And Allaah knows best.
