Marrying off a young daughter by her guardian to an elderly man

Question:
He says: Honorable Shaykh, may Allah grant you success, what is your view regarding one who marries off his young daughter, who is, for example, fifteen years old, to a man who is eighty years old, and who is generally unable to procreate or have intercourse? In fact, her guardian marries her off for the sake of money only.

Answer:
This is a result of modern ideas that make people averse to the marriage of the elderly and averse to plural marriage. There is no harm in her marrying if the husband is righteous, even if he is old. Abu Bakr al-Siddiq (may Allah be pleased with him) married his daughter, who was six years old, to the Messenger of Allah (peace and blessings be upon him), and he was over forty.
So if there is suitability in the husband for her and she has a share in him, there is no objection to marrying the elderly or the young. Do not prevent women from marrying. These are corrupt and bad ideas. Now there is a campaign against marriage, but they come with tricks, saying: do not marry the old man, do not marry the one who has four wives, or three wives, or even if he has a second wife, it is not permissible. They make a fuss about these matters, wanting to prevent marriage. And we carry out what they say and repeat what they say without thinking. Our Shari'ah has made this permissible, and praise be to Allah. It is not permissible for the guardian to marry off a fifteen-year-old girl if the man is not righteous and he is older than her. It is not permissible for him to marry her off to one who is not suitable for her. But if he marries her off to one who has suitability, even if he is older than her, what is the objection?
This is a restriction on what Allah has made permissible, a prohibition of what Allah has made permissible. The criterion is suitability, whether he is old or young. And we do not pay attention to these evil ideas that are being spread for a purpose we do not realize until later. Yes.
