Musnad Ahmad 26:555

Waki' narrated to us, from Isra'il, from Abu Ishaq, from al-Aswad ibn Yazid, from Abdullah, who said: "I recited to the Prophet, peace and blessings of Allah be upon him: 'Hal min mudhakkir' (Is there any who will receive admonition?)." The Prophet, peace and blessings of Allah be upon him, said: "{Hal min muddakir}."
