I dont know Islam always be misinterpreted by the people for their own sake, and their own convenience.

Let me tell you what the holy quran means Allah says in this context in

Surat An-Nisā'

O mankind, fear your Lord, who created you from one soul and created from it its mate and dispersed from both of them many men and women. And fear Allah , through whom you ask one another, and the wombs. Indeed Allah is ever, over you, an Observer

And give to the orphans their properties and do not substitute the defective [of your own] for the good [of theirs]. And do not consume their properties into your own. Indeed, that is ever a great sin.

And if you fear that you will not deal justly with the orphan girls, then marry those that please you of [other] women, two or three or four. But if you fear that you will not be just, then [marry only] one or those your right hand possesses. That is more suitable that you may not incline [to injustice].

And give the women [upon marriage] their [bridal] gifts graciously. But if they give up willingly to you anything of it, then take it in satisfaction and ease.

And do not give the weak-minded your property, which Allah has made a means of sustenance for you, but provide for them with it and clothe them and speak to them words of appropriate kindness.

And whoever does that in aggression and injustice - then We will drive him into a Fire. And that, for Allah , is [always] easy

Where it is Mention that you can marry again and again for your own pleasures. and it is mention in The Quran if fear your Lord ,
Indeed Allah is ever, over you, an Observer

And whoever does that in aggression and injustice - then We will drive him into a Fire. And that, for Allah , is [always] easy

Islam never be wrong in terms of justice but Muslims are used it as per our conveneince
