Imam Sadiq (a.s) told Bahr the water carrier: “O' Bahr! Being good-tempered eases the affairs. Do you want me to tell you a story that all people of Medina know?” He said: “Yes.” Imam Sadiq (a.s) said: “One day when the Prophet of God (a.s) was sitting in the mosque, one of the servants of one of the Ansar – helpers- stood next to him and grabbed his robe. The Prophet (a.s) stood up as a sign of respect but did not say anything. She did not say anything either. This was repeated three times, until the third time she took a string off his robe and returned. The people stopped her and objected to her behavior asking her what she wanted. She said she had been sent to take a string off the Prophet's robe as a blessing in order to cure a patient in their house, but she could not pick it because she got ashamed when the Prophet stood up. She did not want to ask him to do it either, but finally the fourth time around she picked the string.”
