A man marrying another woman due to the unsuitability of the first

Q 1: What is the ruling on a man who marries a second wife and divorces his first one not because his second wife asks him to do so but because of another reason?

A: If it becomes clear for a man that his wife is no longer suitable for him, and that divorce is the correct decision, it is permissible for him to divorce her. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
