[Machine] The Messenger of Allah ﷺ forbade the sale of a debt for another debt. Abu Abd al-Aziz al-Rabadhi, who is Musa ibn Ubaydah, narrated this. And Abu Saad al-Malini informed us, I am Abu Ahmad ibn Adiy al-Hafiz, and al-Qasim ibn Mahdi narrated to us, and Abu Musab narrated from Abdulaziz al-Darawardi, from Musa ibn Ubaydah, who mentioned it in a similar way. Musa said, Nafe' said, and that is the sale of a debt for another debt. Abu Ahmad said, and this is known from Musa ibn Ubaydah from Nafe'. May Allah have mercy on the sheikh. And
