What is the religious ruling on a sister's rejection of a man who proposed to her five times, after her brothers' approval and the recitation of the Fatihah, and then their retraction of their approval?

It is understood from the question that the first engagement was not followed by a marriage contract, and engagement is merely a promise of marriage, and breaking it carries no blame. It is advisable to accept a suitor who possesses characteristics of religiosity and good character, even if he has children or is not handsome, because what matters is piety and good character. For a man of religion and good character will protect a Muslim woman. "No believing man should hate a believing woman; if he dislikes one of her characteristics, he will be pleased with another."
