Question: if a husband were to get married to an second wife would it be appropriate for to ask his first wife before or he could go ahead and just get married and tell her after or if he has to ask for permission before or consults her !?!
Answer: Assalamu alaikum,
He does not have to ask for permission nor is it essential for him to consult her. However, he should speak to her about it and tell her of his intention. If he sees that having a second wife will create problems in his first marriage or it can cause disruption in his first family (that is wife and children), then he should refrain from taking a second wife.
And Allah Knows best.
