A while ago I had a discussion with my friend who is married about having a second, just a general conversation and he was so opposed to it. Because according to him he just didn't see how he would love two people and said he loves his wife too much to even contemplate it and would never do such thing as he knows how his wife's feels about it. Alhamdolillah since then we have both started to practice at a higher level then we used to.
He goes to this salafi mosque local to him, and feels quite strong about being a salafi which is fine and alhamdulilah we don't differ much just a few bits with regards to al walā wal bara but recently we had the exact same discussion about second wife's and his point of view completely changed. He explained that as a man he feels he needs a second wife because Allah SW has made us men into such creature's that it would help him control his desires as a man and he also said a few other things.
He laughed at me when I said that I know we are allowed 4 wife's and it's fine in our Deen, in fact the Prophet saw even had more than one wife, but alhamdulilah am ok with my 1 wife and I really do love my wife and wouldn't want to do something that would cause a rift in a healthy marriage and plus I couldn't take on the extra load of another wife.
I was so gobsmacked with the 360 change of his stance towards this matter especially the way he laughed at me and said "you wouldn't say that when you are overcome by your desires" i.e I'd regret my stance if I sin due to my desires (which btw are being fulfilled by my 1 wife). Seriously though this guy is the type of guy that would die for his wife, like he would call in sick to work so his wife could sleep in and he can watch the kids, or he would send her flowers every other day. But his view has changed so much so that he sees it necessary to have more than one wife and he said that if he had known what he knows now before he got married, maybe he would have married someone else who wouldn't oppose it i.e not his current wife
So my question is; is there something in the teaching of salafism that encourages rather than just teachs about having more than one wife.
