Please, I would like to know the Islamic rulings about a man getting married to a 2nd wife and the right of the first wife in relation to this action.
Hi Sister (sorry for the earlier mistake),
Welcome to our community and I hope you find it full of useful information in shaa Allah
Apologies, I have only just came across your post.
A Muslim man can have up to four wives on the condition that he treats them all fairly; if he does not have the capacity and ability to deal with such justice then he should suffice with one.
This situation can be found in Surah Al Nisaa’ ayah 3 which has a meaning which can be translated as:
“…marry women of your choice, two, or three, or four; but if you fear that you will not be able to deal justly (with them) then only one…” 4:3
This website should also help as to what the rights of the first wife are in shaa Allah. https://www.islamweb.net/en/fatwa/350290/first-wifes-permission-not-condition-for-validity-of-second-marriage
May Allah make it easy for us to follow His laws. Ameen.
