What is the ruling on donating organs from a person who has suffered brain death?

The Shaykh : He says: My cousin had an accident and hit his head, so he was afflicted with brain death. He asked us to donate his organs, so we postponed that until we could ask you and seek your fatwa on the matter. Did I give you a fatwa a moment ago? It was you who sought a fatwa a moment ago? Come, man. What? I will take care of this.
Yes, fine, that is enough, I have understood the answer that this is not permissible, and that the deceased is a trust in your hands, and it is not permissible for you to be negligent regarding any of his organs, due to the saying of the Prophet (peace and blessings be upon him) . Did I understand? Yes. Let us see. And whoever revives a soul, it is as if he has revived all the people. Wait, wait, that is what it means. Whoever revives it, if you find a person drowning in the water and you save him, but this is not that, this is not like that. The student is 'Abd al-Rahman ibn Jum'a, 'Abd al-Rahman Jum'a, yes.
