Is it permissible to divorce or marry another woman due to not enjoying the wife's beauty, despite her being religious and of good character, especially if there has been no childbirth yet?

It is advisable not to divorce a religious and well-mannered wife due to a lack of beauty, because religion and good character are more important in marriage. As the Prophet, peace and blessings be upon him, said: "Marry the religious woman, and may your hands be dusted with success," and "A believing man should not hate a believing woman; if he dislikes one of her characteristics, he will be pleased with another." Similarly, it is impermissible to look at other women and compare them to one's wife, as many of them may lack religiosity and chastity despite their outward beauty. A husband should not seek a wife who is perfect in every way. He may marry another if he is capable of doing so.
