should men ask their wives to marry a second woman

 

Yeah I understand, but I think often these writers also seek to somehow justify plural marriage in contemporary times.  Prior to Islam these marriages were common and Islam only limited the number and sought to ensure justice between the wives.  No conditions such as those commonly stated by writers today were mentioned by Allah or His Prophet.  We many times see written that only if the wife could not have children, or widows in times of war, sickness, etc.  As time passes Muslims begin to adopt these writings as if they have textual basis and there are none- at least to my knowledge. 

 

It is not mandatory for a man to take permission from his first wife but it is mandatory for a man to inform his first wife about the second marraige,
