This question already has an answer here:
Some people claim that a married man cannot marry again till he gets permission from his first wife. I find that hard to believe. As much as I have studied this subject, I have not come across any such prerequisite for second marriage. I have heard about the equality and justness and fairness amongst all the wives but I don't understand how a wife would ever allow to share her love and allow her husband to go to another woman with her permission. (Exceptions may be one in a million).
But considering how little knowledge I have, I am inclined to ask others if they can provide references for such a claim?
Please provide references from Qur'an and Hadith or Sahaba's sayings. You can also provide reference from Four Imam's books/rulings where they put such a restriction.
I am looking for Sunni view but Shia views are welcomed too. (Please mention this along your answer)
P.S. A thought just hit my mind, if in case first wife's permission's requried for the second marriage, then what about the 3rd and 4th marriage? Do we need to ask permission from all the wives?
