Imam al-Sadiq (a.s) has
said: A Bedouin woman passing by the Holy Prophet who was eating on the earth
said, “O Muhammad! I swear by Allah that you eat and sit on the earth like a
servant of Allah.” The Holy Prophet said, “Woe to you! Who is more deserving
than me to be a servant of Allah?” The woman said, “Give a morsel of your food
to me!” The Holy Prophet gave her a morsel. The woman said, “No, give me the
morsel in your mouth!” The Holy Prophet brought out the morsel from his mouth
and gave it to her. The woman never experienced any pain in life until she
died. (Al-Mahasin: 457/2, H 388.)
