Permissibility of marrying a second wife
Question

                Is it permissible for a person who cannot adjust with his current wife to marry a second wife?  He does not want to leave his first wife.
Praise be to Allah.and peace and blessings be upon His Messenger.
It is OK for you to marry a second wife, and in fact this could be the solution to your problem, because Allaah says (interpretation of the meaning):
"… then marry women of your choice, two or three, or four…" [al-Nisaa’ 4:3]
- as long as you are going to treat them equally with regard to where you spend your nights and how much you spend on them. So if you spend one night with one, and the next night with the other, and spend on them equally, there is nothing wrong at all with marrying a second wife.
And Allaah knows best.
