Re: how many wifes is a muslim allowed?
Um no. The Quran sets 4 as the maximum. It also recommends strongly you only take 1 wife if you are fearful of not being fair, since the punishment for being unfair is terrible.
Therefore, really, just save yourself the trouble and stick to 1.
4 as in max or 4 at one time? I have seen one mufti claim the second position of four at ONE TIME.
