Re: If you could be married to more than one guy at the same time..
wow hold your horses right there
whatever you said it completely incorrect and is a complete misinterpretation of Islamic law and teaching at multiple levels
there is no such ruling that says men can only marry up to four women during war and post war times. If you look at Islam as a functioning and look at all sorts of reasons and justifications then you realize there all the things that are allowed and others disallowed because of some reason. Prophet pbuh did not give any reason to any ruling by Allah swt what he gave is the wisdom the word reason must not be associated with rulings of Allah swt because he does not need a reason to make us to such and such. The concept of reason comes in play when we try to explain something that doesnt quite fit our understanding.
There were no rulings in Islam by the end of its completion where any of them were not applicable for people to come.
By you saying not applicable because no reason anymore means that Islam was left incomplete, the prophet pbuh did not tell us what to do in our time and so forth.
