Ibadah Of Marrying More Than One And Hatred Of First Wife For That Ibadah
No, it would not tantamount to hating Ibadah or Hating Allah being worshipped unless the person actually beliefs in that or admits is openly. However, I must point it out again that marrying more than one is not an ibadah, not in any sense the way first marriage could be categorized as ibadah. The premise of the question is not correct and it needs to be supported with a better practical example.
