The basis of the rule that the maidens must not or, at least, should not marry without the consent of their fathers is not that they are considered to be less mature than the boys. Moreover, had Islam considered girls to be immature it would not have regarded the transactions, involving money and properties, made by them independently, as valid. Apart from the legal arguments, this point has a definite philosophy which cannot be ignored. It is not a question of the immaturity or intellectual inadequacy of woman. It is related to a definite aspect of the psychology of the two sexes i.e. man's instinct of alluring and woman's instinct of credulity in regard to man's faithfulness and truthfulness.
Man is after sex and woman is after love.
Man is overpowered by his sexual urge, whereas, woman, according to the psychologists, has a greater capacity of controlling and concealing her desires. It is the melody of love, sincerity and faithfulness which subdues woman and brings her to her knees. That is what we mean by credulity of woman. As long as the woman is a maiden and has had no experience of men, she can easily be lured by his love songs. Professor Reeck, the American psychologist, says that the best sentence which a man can say to a woman is 'Darling, I love you'.
