Anas ibn Malik reported that the Messenger of Allah, may Allah
bless him and grant him peace, visited one of the houses of the Ansar and
ate some food with them. When he left, he asked for a place in the house

his large ears showing. He was told, 'You have made yourself ugly.' He
replied, "The real good is the good of the Next World.'"
