From al-Daylami in al-Irshad: He said:  The Holy Prophet (may Allah bless him and grant him peace) used to patch his own clothes, mend his sandals, milk his ewe, eat with the slaves, sit on the ground, ride a donkey, and carry someone with him; he would not be ashamed to carry his own groceries and other items from the market to his family.  He would shake hands with the rich and the poor alike and he would not take his hand back from the hand of the other person until that person himself withdrew his hand.  He would salute anyone who came to him from the rich or poor, old or young.  He would never look down on what he was offered even if it were a dry date.  He had few possessions, was kind by nature, sociable, cheerful, always smiling but without laughing, always sad, but without frowning, humble without losing self-respect, generous without being extravagant, openhearted and merciful to every Muslim.  He never belched out of being full and he never extended his hand (to something) out of desire (for it) -- ever.
