The first wife's consent is not a condition for polygamy
Question:
"It is common knowledge that Islam permits polygamy. Should the husband ask for the first wife's consent before marrying a second?"
Answer:
"When a husband wants to marry a second wife, it is not obligatory on him to soothe his first wife. However, it is a noble characteristic and a form of intimacy to comfort her and alleviate the agony that a woman may experience in such a situation. This can be achieved through giving her a smile, treating her kindly and talking to her passionately as well as offering her money if it makes her happy. May Allah grant us success! May peace and blessings be upon our Prophet Muhammad, his family and Companions!"
