Islam is the only religion that encourages to marry only 1.

Islam is the only religion that puts an upper limit on polygamy which is 4, but with a condition if the man can be just with all his wives.

It is almost impossible for a human to be just with more than one. Even a mother can't be just with all her children !!! Obviously one of them will be her personal favorite :)

So the point is ... Islam discourages polygamy .... but doesn't restrict. Now why a person marries more than 1 ... he will be answerable to Allah. So if someone really marries to protect a women (or any other noble cause), Allah will be pleased but if he does it only for lust .... he might be punished ... After all Allah knows everything.

So if you marry more than 1 ... you put yourself into a very difficult test (to be just with all of them) and you will be punished if you fail !!!
