The World Federation One Stop Fiqh

Ruling 2435

If, for example, a man has two permanent wives and he stays with one of them one night, it is obligatory for him to also stay with his other wife one in every four nights. Apart from this case, it is not obligatory for him to stay with his wife. However, it is necessary that he does not totally abandon her, and the more precautious and more preferred (al‐aḥwaṭ al‐awlā) [juristic opinion]14 is that a husband should stay with his permanent wife one in every four nights.

14 For practical purposes, a ‘more precautious and more preferred’ juristic opinion is equivalent to recommended precaution.
