Musnad Ahmad 32:1251

'Abd al-Samad narrated to us, Hammam narrated to us, Ishaq narrated to us, from Anas, who said: "I was walking with the Prophet, peace and blessings of Allah be upon him, and he was wearing a Najrani cloak with a thick border. A Bedouin from the people of the desert caught up with him and pulled him by it with a strong pull, until the cloak tore, and its border became embedded in the neck of the Messenger of Allah, peace and blessings of Allah be upon him. Then, from the change in the Messenger of Allah, peace and blessings of Allah be upon him, he ordered something for him, and it was given to him."
