Musannaf Ibn Abi Shayba 13:2707

Abu Bakr narrated to us, he said: Waki’ narrated to us, from Ibn Abi Rawwad, he said: I heard al-Dahhak [regarding the verse]: "And whatever you give for interest to increase within the wealth of people will not increase with Allah," he said: This was for the Prophet, peace and blessings of Allah be upon him, exclusively.
