Silsilat al-Ahadith al-Sahihah

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) sent for Sayyiduna Muawiyah (may Allah be pleased with him) to write something for him. He replied that he was eating food. Then the message was sent again. He replied: He is eating food. The Messenger of Allah (peace and blessings be upon him) said: "May Allah never fill his stomach."
