Is it permissible to marry off a man who is 30 years old, has a strong memory, is healthy in body and appearance, understands matters of marriage but does not comprehend the meaning of marriage, divorce, and the obligatory rights, knowing that he desires to marry?

It is permissible to marry a man of deficient intellect, provided that the guardian and the wife are informed of his deficiency, his lack of understanding of matters related to marriage, divorce, and rights, his ignorance of prayer, and that he is unemployed and cannot distinguish between what benefits him and what harms him. His brother or father must undertake to supervise him and provide for his housing, expenses, the marriage dowry, and its related matters, because this deficiency is considered a defect that can invalidate the marriage contract.
