Second: Mutarrif and Ibn al-Mājishūn hold that if his lack of sound financial judgment has persisted since puberty, none of his transactions is valid. If, however, he loses sound financial judgment after it had been discerned in him, his transactions are valid and binding upon him, unless a sale involves unsound judgment and manifest deception—for example, selling something worth a thousand dinars for a hundred dinars, or the like.

Here too, no distinction is made between whether his lack of sound judgment has persisted since puberty or not. They all agree that if his circumstances are unknown, and neither sound nor unsound financial judgment is established, his transactions are valid and none is to be set aside.

As for one whose father is living, there are eight differing views:
