This is from the calamities that the enemies of the Islamic Legislation have made apparent, as the allowance of polygyny (i.e. multiple wives) is legislatively prescribed. Whatever is similar to that is met with submission, willful compliance, and acceptance. As for having disapproval for he who acquires two wives or more, this does not emanate from anyone except an ignoramus or one who is affected by a doubt hurled into his heart by followers of desires through their different means. Allah says:
فانْكحوا ما طاب لكم من النساء مثنى و ثلاث و رباع فإنْ خفتم ألاّ تعدلوا فواحدة
“Then marry whatever you desire from women, two (women), three (women), or four (women if you so choose and desire that), and if you fear that you cannot be just, then (marry) one…”
Allah’s Messenger -sallahu alayhi wa sallam- married more than one, likewise a large number of Companions. Therefore, polygyny is lawful and allowed, and perhaps it is recommended in a case of he who is not sufficed with one wife and craves multiple wives.
