Re: all these talks of men being polygamous … 
But if you recite the Ayah where it is mentioned, Allah also puts a condition “If you can do justice (among them)” In present times, men don’t have that patience, character, sense, knowledge and wisdom to do justice, like the students of the Prophet (saw) used to have. Many scholar think that it is almost impossible for the present day Muslims to do justice even between two wives.They would have to give exactly the same amount of time to both. If one gets a gift, the other should also get one of the same value…etc.
