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 Allaah.
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.
